Ошибка при установке модулей python

In my case, it is permission problem. The package was somehow installed with root rw permission only, other user just cannot rw to it!

I had the same problem: script with import colorama was throwing and ImportError, but sudo pip install colorama was telling me «package already installed».

My fix: run pip without sudo: pip install colorama. Then pip agreed it needed to be installed, installed it, and my script ran.

My environment is Ubuntu 14.04 32-bit; I think I saw this before and after I activated my virtualenv.

UPDATE: even better, use python -m pip install <package>. The benefit of this is, since you are executing the specific version of python that you want the package in, pip will unequivocally install the package in to the «right» python. Again, don’t use sudo in this case… then you get the package in the right place, but possibly with (unwanted) root permissions.

It’s the python path problem.

In my case, I have python installed in:

/Library/Frameworks/Python.framework/Versions/2.6/bin/python,

and there is no site-packages directory within the python2.6.

The package(SOAPpy) I installed by pip is located

/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/

And site-package is not in the python path, all I did is add site-packages to PYTHONPATH permanently.

Open up Terminal
Type open .bash_profile

In the text file that pops up, add this line at the end:

export PYTHONPATH=$PYTHONPATH:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/

Save the file, restart the Terminal, and you’re done

I was able to correct this issue with a combined approach. First, I followed Chris’ advice, opened a command line and typed ‘pip show packagename’
This provided the location of the installed package.

Next, I opened python and typed ‘import sys’, then ‘sys.path’ to show where my python searches for any packages I import. Alas, the location shown in the first step was NOT in the list.

Final step, I typed ‘sys.path.append(‘package_location_seen_in_step_1’). You optionally can repeat step two to see the location is now in the list.

Test step, try to import the package again… it works.

The downside? It is temporary, and you need to add it to the list each time.

The Python import mechanism works, really, so, either:

Your PYTHONPATH is wrong,
Your library is not installed where you think it is
You have another library with the same name masking this one

I have been banging my head against my monitor on this until a young-hip intern told me the secret is to «python setup.py install» inside the module directory.

For some reason, running the setup from there makes it just work.

To be clear, if your module’s name is «foo»:

[burnc7 (2016-06-21 15:28:49) git]# ls -l
total 1
drwxr-xr-x 7 root root  118 Jun 21 15:22 foo
[burnc7 (2016-06-21 15:28:51) git]# cd foo
[burnc7 (2016-06-21 15:28:53) foo]# ls -l
total 2
drwxr-xr-x 2 root root   93 Jun 21 15:23 foo
-rw-r--r-- 1 root root  416 May 31 12:26 setup.py
[burnc7 (2016-06-21 15:28:54) foo]# python setup.py install
<--snip-->

If you try to run setup.py from any other directory by calling out its path, you end up with a borked install.

DOES NOT WORK:

python /root/foo/setup.py install

DOES WORK:

cd /root/foo
python setup.py install

This problem can also occur with a relocated virtual environment (venv).

I had a project with a venv set up inside the root directory. Later I created a new user and decided to move the project to this user. Instead of moving only the source files and installing the dependencies freshly, I moved the entire project along with the venv folder to the new user.

After that, the dependencies that I installed were getting added to the global site-packages folder instead of the one inside the venv, so the code running inside this env was not able to access those dependencies.

To solve this problem, just remove the venv folder and recreate it again, like so:

$ deactivate
$ rm -rf venv
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

In my case I had run pip install Django==1.11 and it would not import from the python interpreter.

Browsing through pip’s commands I found pip show which looked like this:

> pip show Django
Name: Django
Version: 1.11
...
Location: /usr/lib/python3.4/site-packages
...

Notice the location says ‘3.4’. I found that the python-command was linked to python2.7

/usr/bin> ls -l python
lrwxrwxrwx 1 root root 9 Mar 14 15:48 python -> python2.7

Right next to that I found a link called python3 so I used that. You could also change the link to python3.4. That would fix it, too.

In my case, I assumed a package was installed because it showed up in the output of pip freeze. However, just the site-packages/*.dist-info folder is enough for pip to list it as installed despite missing the actual package contents (perhaps from an accidental deletion). This happens even when all the path settings are correct, and if you try pip install <pkg> it will say «requirement already satisfied».

The solution is to manually remove the dist-info folder so that pip realizes the package contents are missing. Then, doing a fresh install should re-populate anything that was accidentally removed

When you install via easy_install or pip, is it completing successfully? What is the full output? Which python installation are you using? You may need to use sudo before your installation command, if you are installing modules to a system directory (if you are using the system python installation, perhaps). There’s not a lot of useful information in your question to go off of, but some tools that will probably help include:

echo $PYTHONPATH and/or echo $PATH: when importing modules, Python searches one of these environment variables (lists of directories, : delimited) for the module you want. Importing problems are often due to the right directory being absent from these lists
which python, which pip, or which easy_install: these will tell you the location of each executable. It may help to know.
Use virtualenv, like @JesseBriggs suggests. It works very well with pip to help you isolate and manage the modules and environment for separate Python projects.

I had this exact problem, but none of the answers above worked. It drove me crazy until I noticed that sys.path was different after I had imported from the parent project. It turned out that I had used importlib to write a little function in order to import a file not in the project hierarchy. Bad idea: I forgot that I had done this. Even worse, the import process mucked with the sys.path—and left it that way. Very bad idea.

The solution was to stop that, and simply put the file I needed to import into the project. Another approach would have been to put the file into its own project, as it needs to be rebuilt from time to time, and the rebuild may or may not coincide with the rebuild of the main project.

I had this problem with 2.7 and 3.5 installed on my system trying to test a telegram bot with Python-Telegram-Bot.

I couldn’t get it to work after installing with pip and pip3, with sudo or without. I always got:

Traceback (most recent call last):
  File "telegram.py", line 2, in <module>
    from telegram.ext import Updater
  File "$USER/telegram.py", line 2, in <module>
    from telegram.ext import Updater
ImportError: No module named 'telegram.ext'; 'telegram' is not a package

Reading the error message correctly tells me that python is looking in the current directory for a telegram.py. And right, I had a script lying there called telegram.py and this was loaded by python when I called import.

Conclusion, make sure you don’t have any package.py in your current working dir when trying to import. (And read error message thoroughly).

I had a similar problem using Django. In my case, I could import the module from the Django shell, but not from a .py which imported the module.
The problem was that I was running the Django server (therefore, executing the .py) from a different virtualenv from which the module had been installed.

Instead, the shell instance was being run in the correct virtualenv. Hence, why it worked.

This often happens when module is installed to an older version of python or another directory, no worries as solution is simple.
— import module from directory in which module is installed.
You can do this by first importing the python sys module then importing from the path in which the module is installed

import sys
sys.path.append("directory in which module is installed")

import <module_name>

I have solved my issue that same libraries were working fine in one project(A) but importing those same libraries in another project(B) caused error. I am using Pycharm as IDE at Windows OS.
So, after trying many potential solutions and failing to solve the issue, I did these two things (deleted «Venv» folder, and reconfigured interpreter):

1-In project(B), there was a folder named(«venv»), located in External Libraries/. I deleted that folder.

2-Step 1 (deleting «venv» folder) causes error in Python Interpreter Configuration, and
there is a message shown at top of screen saying «Invalid python interpreter selected
for the project» and «configure python interpreter», select that link and it opens a
new window. There in «Project Interpreter» drop-down list, there is a Red colored line
showing previous invalid interpreter. Now, Open this list and select the Python
Interpreter(in my case, it is Python 3.7). Press «Apply» and «OK» at the bottom and you
are good to go.

Note: It was potentially the issue where Virtual Environment of my Project(B) was not recognizing the already installed and working libraries.

However, now I’m trying to download the nltk library, and neither is getting the job done.

I found it sufficient to specify the pypi host as trusted. Example:

pip install --trusted-host pypi.python.org pytest-xdist

  Could not find a version that satisfies the requirement pytest-cov (from versions: )
No matching distribution found for pytest-cov

Update April 2018:
To anyone getting the TLSV1_ALERT_PROTOCOL_VERSION error: it has nothing to do with trusted-host/verification issue of the OP or this answer. Rather the TLSV1 error is because your interpreter does not support TLS v1.2, you must upgrade your interpreter. See for example https://news.ycombinator.com/item?id=13539034, http://pyfound.blogspot.ca/2017/01/time-to-upgrade-your-python-tls-v12.html and https://bugs.python.org/issue17128.

Update Feb 2019:
For some it may be sufficient to upgrade pip. If the above error prevents you from doing this, use get-pip.py. E.g. on Linux,

curl https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

I used pip3 version 9.0.1 and was unable to install any packages recently via the commandpip3 install.

Mac os version: EI Captain 10.11.5.

python version: 3.5

I tried the command:

curl https://bootstrap.pypa.io/get-pip.py | python

It didn’t work for me.

So I uninstalled the older pip and installed the newest version10.0.0 by entering this:

python3 -m pip uninstall pip setuptools

Now my problem was solved.
If you are using the python2, you can substitute the python3 with python. I hope it also works for you.

By the way, for some rookies like me, you have to enter the code:
sudo -i

to gain the root right 🙂 Good luck!

You’re probably seeing this bug; see also here.

The easiest workaround is to downgrade pip to one that doesn’t use SSL: easy_install pip==1.2.1. This loses you the security benefit of using SSL. The real solution is to use a Python distribution linked to a more recent SSL library.

To install any other package I have to use the latest version of pip, since the 9.0.1 has this SSL problem. To upgrade the pip by pip itself, I have to solve this SSL problem first.
To jump out of this endless loop, I find this only way that works for me.

Find the latest version of pip in this page:
https://pypi.org/simple/pip/
Download the .whl file of the latest version.
Use pip to install the latest pip. (Use your own latest version here)

sudo pip install pip-10.0.1-py2.py3-none-any.whl

Now the pip is the latest version and can install anything.

You can also use conda to install packages: See http://conda.pydata.org

conda install nltk

The best way to use conda is to download Miniconda, but you can also try

pip install conda

I did the following on Windows 7 to solve this problem.

c:Program FilesPython36Scripts> pip install beautifulsoup4 —trusted-host *

The —trusted-host seems to fix the SSL issue and * means every host.

Of course this does not work because you get other errors since there is no version that satisfies the requirement beautifulsoup4, but I don’t think that issue is related to the general question.

Just uninstall and reinstall pip packages it will workout for you guys.

Mac os version: high Sierra 10.13.6

python version: 3.7

So I uninstalled the older pip and installed the newest version10.0.0 by entering this:

python3 -m pip uninstall pip setuptools

curl https://bootstrap.pypa.io/get-pip.py | python3

Now my problem was solved. If you are using the python2, you can substitute the python3 with python. I hope it also works for you.

If it is only about nltk, I once faced similar problem. Try following guide for installation.
Install NLTK

If you are sure it doesn’t work with any other module, you may have problem with different versions of Python installed.

Or Give It a Try to see if it says pip is already installed.:

sudo apt-get install python-pip python-dev build-essential

and see if it works.

I had this with PyCharm and upgrading pip to 10.0.1 broke pip with «‘main’ not found in module» error.

I could solve this problem by installing pip 9.0.3 as seen in some other thread. These are the steps I did:

Downloaded 9.0.3 version of pip from https://pypi.org/simple/pip/ (since pip couldn’t be used to install it).
Install pip 9.0.3 from tar.gz
python -m pip install pip-9.0.3.tar.gz

I found it sufficient to specify the pypi host as trusted. Example:

pip install --trusted-host pypi.python.org pytest-xdist
pip install --trusted-host pypi.python.org --upgrade pip

This solved the following error:

  Could not fetch URL https://pypi.python.org/simple/pytest-cov/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600) - skipping
  Could not find a version that satisfies the requirement pytest-cov (from versions: )
No matching distribution found for pytest-cov

Update Feb 2019:
For some it may be sufficient to upgrade pip. If the above error prevents you from doing this, use get-pip.py. E.g. on Linux,

curl https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

I used pip version 9.0.1 and had the same issue, all the answers above didn’t solve the problem, and I couldn’t install python / pip with brew for other reasons.

Upgrading pip to 9.0.3 solved the problem. And because I couldn’t upgrade pip with pip I downloaded the source and installed it manually.

Download the correct version of pip from — https://pypi.org/simple/pip/
sudo python3 pip-9.0.3.tar.gz — Install pip

I used pip3 version 9.0.1 and was unable to install any packages recently via the commandpip3 install.

Mac os version: EI Captain 10.11.5.

python version: 3.5

I tried the command:

curl https://bootstrap.pypa.io/get-pip.py | python

It didn’t work for me.

So I uninstalled the older pip and installed the newest version10.0.0 by entering this:

python3 -m pip uninstall pip setuptools
curl https://bootstrap.pypa.io/get-pip.py | python3

Now my problem was solved.
If you are using the python2, you can substitute the python3 with python. I hope it also works for you.

By the way, for some rookies like me, you have to enter the code:
sudo -i

to gain the root right 🙂 Good luck!

Что означает ошибка ModuleNotFoundError: No module named

Python ругается, что не может найти нужный модуль

Ситуация: мы решили заняться бигдатой и обработать большой массив данных на Python. Чтобы было проще, мы используем уже готовые решения и находим нужный нам код в интернете, например такой:

import numpy as np
x = [2, 3, 4, 5, 6]
nums = np.array([2, 3, 4, 5, 6])
type(nums)
zeros = np.zeros((5, 4))
lin = np.linspace(1, 10, 20)

Копируем, вставляем в редактор кода и запускаем, чтобы разобраться, как что работает. Но вместо обработки данных Python выдаёт ошибку:

❌ModuleNotFoundError: No module named numpy

Странно, но этот код точно правильный: мы его взяли из блога разработчика и, по комментариям, у всех всё работает. Откуда тогда ошибка?

Что это значит: Python пытается подключить библиотеку, которую мы указали, но не может её найти у себя.

Когда встречается: когда библиотеки нет или мы неправильно написали её название.

Что делать с ошибкой ModuleNotFoundError: No module named

Самый простой способ исправить эту ошибку — установить библиотеку, которую мы хотим подключить в проект. Для установки Python-библиотек используют штатную команду pip или pip3, которая работает так: pip install <имя_библиотеки>. В нашем случае Python говорит, что он не может подключить библиотеку Numpy, поэтому пишем в командной строке такое:

pip install numpy

Это нужно написать не в командной строке Python, а в командной строке операционной системы. Тогда компьютер скачает эту библиотеку, установит, привяжет к Python и будет ругаться на строчку в коде import numpy.

Ещё бывает такое, что библиотека называется иначе, чем указано в команде pip install. Например, для работы с телеграм-ботами нужна библиотека telebot, а для её установки надо написать pip install pytelegrambotapi. Если попробовать подключить библиотеку с этим же названием, то тоже получим ошибку:

Что означает ошибка ModuleNotFoundError: No module named

А иногда такая ошибка — это просто невнимательность: пропущенная буква в названии библиотеки или опечатка. Исправляем и работаем дальше.

Вёрстка:

Кирилл Климентьев

Источник

В Python может быть несколько причин возникновения ошибки ModuleNotFoundError: No module named ...:

Модуль Python не установлен.
Есть конфликт в названиях пакета и модуля.
Есть конфликт зависимости модулей Python.

Рассмотрим варианты их решения.

Модуль не установлен

В первую очередь нужно проверить, установлен ли модуль. Для использования модуля в программе его нужно установить. Например, если попробовать использовать numpy без установки с помощью pip install будет следующая ошибка:

Traceback (most recent call last):
   File "", line 1, in 
 ModuleNotFoundError: No module named 'numpy'

Для установки нужного модуля используйте следующую команду:

pip install numpy
# или
pip3 install numpy

Или вот эту если используете Anaconda:

conda install numpy

Учтите, что может быть несколько экземпляров Python (или виртуальных сред) в системе. Модуль нужно устанавливать в определенный экземпляр.

Конфликт имен библиотеки и модуля

Еще одна причина ошибки No module named — конфликт в названиях пакета и модуля. Предположим, есть следующая структура проекта Python:

demo-project
 └───utils
         __init__.py
         string_utils.py
         utils.py

Если использовать следующую инструкцию импорта файла utils.py, то Python вернет ошибку ModuleNotFoundError.



>>> import utils.string_utils

Traceback (most recent call last):

   File "C:demo-projectutilsutils.py", line 1, in

     import utils.string_utils

 ModuleNotFoundError: No module named 'utils.string_utils';

 'utils' is not a package

В сообщении об ошибке сказано, что «utils is not a package». utils — это имя пакета, но это также и имя модуля. Это приводит к конфликту, когда имя модуля перекрывает имя пакета/библиотеки. Для его разрешения нужно переименовать файл utils.py.

Иногда может существовать конфликт модулей Python, который и приводит к ошибке No module named.

Следующее сообщение явно указывает, что _numpy_compat.py в библиотеке scipy пытается импортировать модуль numpy.testing.nosetester.

Traceback (most recent call last):
   File "C:demo-projectvenv
Libsite-packages
         scipy_lib_numpy_compat.py", line 10, in
     from numpy.testing.nosetester import import_nose
 ModuleNotFoundError: No module named 'numpy.testing.nosetester'

Ошибка ModuleNotFoundError возникает из-за того, что модуль numpy.testing.nosetester удален из библиотеки в версии 1.18. Для решения этой проблемы нужно обновить numpy и scipy до последних версий.

pip install numpy --upgrade
pip install scipy --upgrade

Резюме :

how fix pip is not recognized windows command prompt

При установке пакетов Python в командной строке вы можете получить сообщение об ошибке «pip не распознается как внутренняя или внешняя команда, работающая программа или командный файл». Как решить проблему? MiniTool покажу вам некоторые методы в этом посте.

PIP не распознается

PIP, Pip Installs Package, представляет собой стандартную систему управления пакетами. Он используется для установки и обработки программных пакетов, написанных на Python. По умолчанию в большинстве версий Python установлен PIP.

При установке пакетов Python в окне командной строки Windows покажет вам ошибку, в которой говорится, что «’pip’ не распознается как внутренняя или внешняя команда, работающая программа или командный файл».

Основные причины того, что PIP не распознается, заключаются в том, что установка PIP не добавляется в системную переменную или установка неправильно добавлена в ваш PATH. Чтобы решить эту проблему, вы можете использовать следующие методы.

Исправления для PIP Not Recognized

Проверьте, добавлен ли PIP в переменную PATH

Во-первых, вы должны знать, добавлена ли ваша установка PIP в переменную PATH. Просто сделайте это, выполнив следующие действия:

Добавить PIP в переменную PATH

Вот три варианта выполнения этой работы: использовать графический интерфейс Windows, командную строку и исполняемый установщик Python.

Графический интерфейс Windows

Команда «Выполнить» обеспечивает удобство доступа к некоторым конкретным программам. В этом посте показано 6 способов открыть окно «Выполнить».

Шаг 1. Запустите командную строку.

Шаг 3: Затем запустите установочный пакет Python, чтобы проверить, исправлено ли «PIP не распознается как внутренняя или внешняя команда».

Использовать исполняемый установщик Python

Шаг 1: запустить python –version в окне CMD, чтобы проверить установленную версию Python.

Шаг 2: Перейдите на Python.org, чтобы загрузить ту же версию исполняемого установщика.

Шаг 4: Убедитесь, что выбрана опция pip.

Заключительные слова

У вас есть «PIP не распознанная команда»? Попробуйте исправить это, следуя приведенным выше методам, и мы надеемся, что вы легко избавитесь от проблемы.

нашёл решение проблемы, вроде (ну по крайней мере этот импорт больше не подсвечивается жёлтым в VSC и не просит починить) итак к сути: пишем pip install cryptohash и заменяем from Crypto.Hash import SHA512 на from cryptohash import sha512 (в моём случае) программу не тестировал, ещё не пофиксил другие проблемы, поэтому работоспособность программы с этим методом незнаю.

Решение проблем с модулями и пакетами Python

Я с завидной регулярностью сталкиваюсь со всевозможными ошибками, так или иначе связанными с модулями Python. Существует огромное количество разнообразных модулей Python, которые разработчики активно используют, но далеко не всегда заботятся об установке зависимостей. Некоторые даже не удосуживаются их документировать. Параллельно существует две мажорные версии Python: 2 и 3. В разных дистрибутивах отдано предпочтение одной или другой версии, по этой причине самостоятельно установленную программу в зависимости от дистрибутива нужно при запуске предварять python или python2/python3. Например:

Причём обычно не происходит никаких проверок и угадали ли вы с выбором версии или нет вы узнаете только при появлении первых ошибок, вызванных неправильным синтаксисом программного кода для данной версии.

Также прибавляет путаницу то, что модули можно установить как из стандартного репозитория дистрибутивов, так и с помощью pip (инструмент для установки пакетов Python).

Цель этой заметки — рассмотреть некоторые характерные проблемы модулей Python. Все возможные ошибки вряд ли удастся охватить, но описанное здесь должно помочь понять, в каком примерно направлении двигаться.

12 1

Отсутствие модуля Python

Большинство ошибок модулей Python начинаются со строк:

В них трудно разобраться, поэтому поищите фразы вида:

За ними следует название модуля.

Поищите по указанному имени в системном репозитории, или попробуйте установить командой вида:

Пакет Python установлен, но программа его не видит

Причина может быть в том, что вы установили модуль для другой версии. Например, программа написана на Python3, а вы установили модуль с этим же названием, но написанный на Python2. В этом случае он не будет существовать для программы. Поэтому нужно правильно указывать номер версии.

Команда pip также имеет свои две версии: pip2 и pip3. Если версия не указана, то это означает, что используется какая-то из двух указанных (2 или 3) версий, которая является основной в системе. Например, сейчас в Debian и производных по умолчанию основной версией Python является вторая. Поэтому в репозитории есть два пакета: python-pip (вторая версия) и python3-pip (третья).

В Arch Linux и производных по умолчанию основной версией является третья, поэтому в репозиториях присутствует пакет python-pip (третья версия) и python2-pip (вторая).

Это же самое относится к пакетам Python и самому Python: если версия не указана, значит имеется ввиду основная для вашего дистрибутива версия. По этой причине многие пакеты в репозитории присутствуют с двумя очень похожими названиями.

Установлена новая версия модуля, но программа видит старую версию

Я несколько раз сталкивался с подобными необъяснимыми ошибками.

Иногда помогает удаление модуля командой вида:

Также попробуйте удалить его используя системный менеджер пакетов.

Если модуль вам нужен, попробуйте вновь установить его и проверьте, решило ли это проблему.

Если проблема не решена, то удалите все файлы модуля, обычно они расположены в папках вида:

Ошибки с фразой «AttributeError: ‘NoneType’ object has no attribute»

Ошибки, в которых присутствует слово AttributeError, NoneType, object has no attribute обычно вызваны не отсутствием модуля, а тем, что модуль не получил ожидаемого аргумента, либо получил неправильное число аргументов. Было бы правильнее сказать, что ошибка вызвана недостаточной проверкой данных и отсутствием перехвата исключений (то есть программа плохо написана).

В этих случаях обычно ничего не требуется дополнительно устанавливать. В моей практике частыми случаями таких ошибок является обращение программы к определённому сайту, но сайт может быть недоступен, либо API ключ больше недействителен, либо программа не получила ожидаемые данные по другим причинам. Также программа может обращаться к другой программе, но из-за ошибки в ней получит не тот результат, который ожидала, и уже это вызывает приведённые выше ошибки, которые мы видим.

Опять же, хорошо написанная программа в этом случае должна вернуть что-то вроде «информация не загружена», «работа программы N завершилась ошибкой» и так далее. Как правило, нужно разбираться с причиной самой первой проблемы или обращаться к разработчику.

Модуль установлен, но при обновлении или обращении к нему появляется ошибки

Это самая экзотическая ошибка, которая вызвана, видимо, повреждением файлов пакета. К примеру, при попытке обновления я получал ошибку:

При этом сам модуль установлен как следует из самой первой строки.

Проблема может решиться удалением всех файлов пакета (с помощью rm) и затем повторной установки.

К примеру в рассматриваемом случае, удаление:

После этого проблема с модулем исчезла.

Заключение

Пожалуй, это далеко не полный «справочник ошибок Python», но если вы можете сориентироваться, какого рода ошибка у вас возникла:

Так вот, если вы хотя бы примерно поняли главную причину, то вам будет проще понять, в каком направлении двигаться для её решения.

Ошибка «PIP» или «Python» не является внутренней или внешней командой Windows 10

Сегодня поговорим об установке Python и о первых проблемах с которыми могут столкнуться начинающие программисты. После установки Python все советую проверит правильность его установки введя в командной строке Python, после этого вы должны увидеть установленную версию питона. Так же вы сможете вводим простенькие команды и выполнять их через командную строку например, введя print(«привет»), код должен выполниться и отобразить просто «Привет».

Для установки различных модулей используется PIP, например, для установки requests в командной строке нужно ввести pip install requests. Вообще большинство пользователей после установки питона и введя в командной строке «PIP» или «Python» получает сообщение об ошибке «не является внутренней или внешней командой, исполняемой программой или пакетным файлом».

Решение данный проблемы очень простое, в интернете очень много ответов, но все они очень краткие, сжатые, без скриншотов. Разобраться новичку будет достаточно сложно. Большинство ответов имеют вот такой вид

«Вам нужно установить путь к pip в переменные окружения»

Думаю новичку это абсолютно ни о чем не говорит, он еще больше запутается. Поэтому я решил подробно описать решение данной проблемы.

Простое решение проблемы в Windows 10

И так при вводе в командной строке PIP вы видите сообщение.

«PIP» не является внутренней или внешней командой, исполняемой программой или пакетным файлом

1 41

Тоже самое и с Python

«Python» не является внутренней или внешней командой, исполняемой программой или пакетным файлом

2 31

Вам нужно добавить значения в переменную Path, рассказывать что это не буду, просто открываем свойства компьютера и выбираем «Дополнительные параметры системы».

3 28

Далее в свойствах системы переходим во вкладку «Дополнительно» и снижу нажимаем «Переменные среды».

4 21

В открывшемся окне в верхней части отмечаем переменную «Path» и нажимаем изменить.

5 18

В поле «Значение переменной» дописываем путь до папки в которой у вас установлен Питон, в моем случае это С:Python, так же нужно указать путь до папки где лежит файл pip.exe у меня это С:PythonScripts. Дописываем через ; вот так.

Рекомендую изменять стандартный путь установки Питона на С:Python.

7 11

Теперь проверяем результат запускаем командную строку и пишем сначала «PIP».

8 8

Потом пробуем написать «Python», после шеврона (>>>) можно уже написать какой нибудь код например, print(«Привет!»).

9 3

Если выше описанное для вас сложно, то можно переустановить сам Питон, отметив в главном окне пункт «Add Python 3.9 to PATH».

6 15

В процессе установки все пути будут прописаны автоматически. Вот так можно избавиться от ошибки «не является внутренней или внешней командой, исполняемой программой или пакетным файлом», которая появляется в командной строке при вводе «PIP» или «Python».

You might encounter a problem when installing a Python package in the project settings or in the Python Package tool window. Eventually, most of the issues are out of IDE control as PyCharm uses the pip package manager to perform the actual installation.

This article provides troubleshooting tips and covers some typical cases.

Install a package using the Terminal

The most viable troubleshooting action is to try installing the problematic package on the selected Python interpreter using the terminal. If you get an identical error message, then the problem is not in the IDE and you should review the rationales and typical cases, or search for a solution on the Internet.

Install a package on a virtual environment

Press Ctrl+Alt+S to open the IDE settings and select .
Expand the list of the available interpreters and click Show All.
Locate the target interpreter and press .

Copy or memorize the path of the virtual environment and close the dialogs.
Open the terminal and run the following commands:

source <venv path>/bin/activate
pip install <package name>
Inspect and parse the results.

Install a package on a Conda environment

Open the terminal and run the following commands:

Conda < 4.6	Conda >= 4.6
activate <conda env name> conda install <package name>	conda activate <conda env name> conda install <package name>

Conda < 4.6	Conda >= 4.6
source activate <conda env name> conda install <package name>	conda activate <conda env name> conda install <package name>

See Conda documentation for more information on how to activate an environment.

Installing a Python package on a virtual environment

One of the possible failure cases occurs when the target package is not available in the repositories supported by the Conda package manager.

Fail to install a package on a Conda environment

Inspect and parse the results.

Install a package on a system interpreter

To check the path of the currently selected system interpreter that you were trying to install a package on, press Ctrl+Alt+S and go to .
Expand the list of the project interpreters and scroll it down, then select the item.
Locate the interpreter and press .

Copy or memorize the path of the environment and close the dialogs.
Open the terminal and run the following commands:

cd <interpreter path>
-m pip install <package name>

You might need the admin privileges to install packages on a system interpreter.
Inspect and parse the results.

Parse the results

Result	Action
The package cannot be installed because the Python version doesn’t satisfy the package requirement.	Try to create another Python interpreter that is based on the Python version that meets the requirement.
The package cannot be installed because you don’t have permissions to install it.	Try to install the package using super-user privileges, for example, `sudo pip install <package name>`.
The package cannot be installed because the package is not available in the repository that is supported by the selected package manager. Example: you’re trying to install a package that is not available in the Conda package manager repositories.	Try to configure another type of Python interpreter for your project and install the package on it. See how to add and modify a Python interpreter in Configure a Python interpreter.
The package cannot be installed and it matches one of the typical package installation failure cases.	Check the cases and apply related workarounds.
The package is successfully installed.	File an issue in the PyCharm issue tracker and provide explicit details about the case including all console output, error messages, and screenshots indicating that you tried to install the package on the same interpreter in the terminal and in the project settings or in the Python Packages tool window.

ModuleNotFoundError: no module named Python Error [Fixed]

When you try to import a module in a Python file, Python tries to resolve this module in several ways. Sometimes, Python throws the ModuleNotFoundError afterward. What does this error mean in Python?

As the name implies, this error occurs when you’re trying to access or use a module that cannot be found. In the case of the title, the «module named Python» cannot be found.

Python here can be any module. Here’s an error when I try to import a numpys module that cannot be found:

import numpys as np

Here’s what the error looks like:

Here are a few reasons why a module may not be found:

you do not have the module you tried importing installed on your computer
you spelled a module incorrectly (which still links back to the previous point, that the misspelled module is not installed)…for example, spelling numpy as numpys during import
you use an incorrect casing for a module (which still links back to the first point)…for example, spelling numpy as NumPy during import will throw the module not found error as both modules are «not the same»
you are importing a module using the wrong path

How to fix the ModuleNotFoundError in Python

As I mentioned in the previous section, there are a couple of reasons a module may not be found. Here are some solutions.

1. Make sure imported modules are installed

Take for example, numpy. You use this module in your code in a file called «test.py» like this:

import numpy as np

arr = np.array([1, 2, 3])

print(arr)

If you try to run this code with python test.py and you get this error:

ModuleNotFoundError: No module named "numpy"

Then it’s most likely possible that the numpy module is not installed on your device. You can install the module like this:

python -m pip install numpy

When installed, the previous code will work correctly and you get the result printed in your terminal:

[1, 2, 3]

2. Make sure modules are spelled correctly

In some cases, you may have installed the module you need, but trying to use it still throws the ModuleNotFound error. In such cases, it could be that you spelled it incorrectly. Take, for example, this code:

import nompy as np

arr = np.array([1, 2, 3])

print(arr)

Here, you have installed numpy but running the above code throws this error:

ModuleNotFoundError: No module named "nompy"

This error comes as a result of the misspelled numpy module as nompy (with the letter o instead of u). You can fix this error by spelling the module correctly.

3. Make sure modules are in the right casing

Similar to the misspelling issue for module not found errors, it could also be that you are spelling the module correctly, but in the wrong casing. Here’s an example:

import Numpy as np

arr = np.array([1, 2, 3])

print(arr)

For this code, you have numpy installed but running the above code will throw this error:

ModuleNotFoundError: No module named 'Numpy'

Due to casing differences, numpy and Numpy are different modules. You can fix this error by spelling the module in the right casing.

4. Make sure you use the right paths

In Python, you can import modules from other files using absolute or relative paths. For this example, I’ll focus on absolute paths.

When you try to access a module from the wrong path, you will also get the module not found here. Here’s an example:

Let’s say you have a project folder called test. In it, you have two folders demoA and demoB.

demoA has an __init__.py file (to show it’s a Python package) and a test1.py module.

demoA also has an __init__.py file and a test2.py module.

Here’s the structure:

└── test
    ├── demoA
        ├── __init__.py
    │   ├── test1.py
    └── demoB
        ├── __init__.py
        ├── test2.py

Here are the contents of test1.py:

def hello():
  print("hello")

And let’s say you want to use this declared hello function in test2.py. The following code will throw a module not found error:

import demoA.test as test1

test1.hello()

This code will throw the following error:

ModuleNotFoundError: No module named 'demoA.test'

The reason for this is that we have used the wrong path to access the test1 module. The right path should be demoA.test1. When you correct that, the code works:

import demoA.test1 as test1

test1.hello()
# hello

Wrapping up

For resolving an imported module, Python checks places like the inbuilt library, installed modules, and modules in the current project. If it’s unable to resolve that module, it throws the ModuleNotFoundError.

Sometimes you do not have that module installed, so you have to install it. Sometimes it’s a misspelled module, or the naming with the wrong casing, or a wrong path. In this article, I’ve shown four possible ways of fixing this error if you experience it.

I hope you learned from it 🙂

It’s not uncommon for new Pythonistas to have trouble installing packages and using their modules. Frustrating errors like this often arise, even if you think you’ve installed a package properly:

>>>

ImportError: No module named <package_name>

This is caused by the fact that the version of Python you’re running your script with is not configured to search for modules where you’ve installed them. This happens when you use the wrong installation of pip to install packages.

In general, each Python installation comes bundled with its own pip executable, used for installing packages. By default, that pip executable will install packages in a location where that specific Python installation can find them.

The problem is that it’s very common to have multiple Python interpreters installed (and by extension, multiple pip executables.) Depending on your shell’s PATH, running pip may invoke the pip executable linked to the version of Python you’re using, or to a different one. If the wrong pip is invoked, then the packages it installs will likely not be visible to the Python interpreter you’re using, causing the ImportError.

To use the version of pip specific to your desired Python version, you can use python -m pip. Here, python is the path to the desired Python interpreter, so something like /usr/local/bin/python3.7 -m pip will use the pip executable for /usr/local/bin/python3.7. However, this still has its limitations.

There are also other ways to get around this issue. You can modify your shell’s PATH so it uses the correct pip executable, or change the PYTHONPATH so that your desired version of Python can find the packages located in a different directory. But these can all get messy fast.

Instead, virtual environments are often used to isolate Python installations from one another. A virtual environment contains, among other things, a Python interpreter, a pip executable, and a site-packages directory, which is the standard location for most packages downloaded with pip.

By activating a virtual environment within your shell, you expose it to only the pip and Python executables installed within your virtual environments, ensuring that the right versions of both applications are invoked and that packages are always installed to the correct location. Virtual environments also allow you to run different versions of the same package with different projects, something not possible if you are using a global Python installation.

There are many different virtual environments to choose from. This course uses Conda, bundled with Anaconda. You can learn more about virtual environments in Working With Python Virtual Environments.

00:00

A common error that new Pythonistas will come across is that the packages they think they’ve installed are not actually being recognized by Python. This will present itself as an ImportError, meaning that the module you’ve tried to import cannot be located. To learn why this is, we have to take a little tour around our operating system.

00:25

When you run a Python program, what you’re really doing is running the Python interpreter and passing it your Python script to interpret and run. The Python interpreter is simply an executable file located somewhere within your system, meaning that it’s literally a program whose job it is to run your Python program. It’s kind of trippy if you think about it. On Windows, this is called python.exe, and on Mac and other Unix environments, it’s just an executable called python.

01:01

There’s a good chance that you’ve got multiple Python interpreters installed. In fact, macOS and most Linux distributions come bundled with an older version of Python, Python 2, which is used for internal system functionality.

01:17

That’s why—if you’ve ever set up a brand new macOS installation and tried to run Python in the terminal—you’ll see a prompt for Python 2. Aside from this built-in Python, you can install other Python versions, like Python 3—or more specifically, 3.7 or 3.8—and they will all live in different locations on your system.

01:42

This is important because new Python versions are not entirely backwards compatible with old versions. Just look at Python 2 versus 3 and how they differ regarding printing to stdout (standard out).

01:56

If you code a program with Python 3 and try to run it with 2, all of your print statements—among other things—will break. The same will happen if you code for Python 2 and try to run it in 3. Apple can’t replace Python 2 with 3 in macOS because the inner workings of macOS still rely on functionality that’s present in Python 2, and that functionality might not exist—or it’ll just be different—in Python 3.

02:28

It’s not worth their time to re-engineer the OS to use Python 3, so they just leave it alone.

02:37

Having the ability to install different Python interpreters on one system is great for compatibility with older software, but it can complicate things when trying to develop new software. That’s because almost every Python interpreter comes bundled with its own version of pip, the package manager you’ll learn about in the rest of this course.

03:00

In that pip application, we’ll install its packages to a specific folder on disk often called site-packages, which sometimes corresponds to a single pip executable.

03:14

This means that invoking the wrong pip executable within your terminal will result in packages being installed in the wrong location. If I accidentally run the pip executable that came with my Python 3.7 installation, the packages it installed may not be searched for by Python 3 because it may install to a different site-packages/ folder.

03:40

So then, how do we fix this? There are many ways around this—for example, by modifying your shell’s path so that it uses the correct pip executable, or changing the Python path so that your desired version of Python can find the packages located somewhere else.

03:58

But these can all get messy pretty quickly, so instead, I almost always recommend using what’s called a virtual environment.

04:09

A virtual environment is a folder containing—among many things—a Python interpreter for a specific version of Python, a pip executable for installing and managing packages, and a site-packages/ folder that corresponds to that exact Python interpreter and pip executable.

04:30

Everything you need to develop your application is self-contained within this folder, isolated from any other Python installations you may have on your system.

04:41

In fact, virtual environments often allow you to activate them from within the shell, temporarily blinding the shell from any other versions of pip and Python installed on your system.

04:55

And, you can have many different virtual environments using different Python versions and different sets of packages. A common practice is to create a different virtual environment for each Python project you work on. This is especially helpful when two different projects require different versions of the same package.

05:17

Having a separate virtual environment for each project will allow each one to use a different version of the package.

05:26

There are many tools you can use to create and manage virtual environments. My personal favorite is called Conda, which is often used in data science and scientific computing. Conda comes as a part of Anaconda, which gives you access to not only Python packages that can be installed with pip, but also its own package manager and package repository.

05:52

This is a course on pip, so I’m not going to go any further in-depth on virtual environments. If you’re interested in learning more, we’ve got a great article on realpython.com that will get you up and running with virtual environments.

06:07

I’ll have a link for that down in the video notes below. You don’t have to use a virtual environment to follow along, but I recommend doing so. It’s also important to note that while Anaconda does come with its own package manager, I won’t be using it in this course.

06:26

I’ll just use Anaconda to create a virtual environment with Python and pip.

06:32

Then, I’ll use pip as the package manager for our new virtual environment.
