Here, I will show you how to fix the error “Defaulting to user installation because normal site-packages is not writeable” while installing a package in Python using pip command.
I faced this issue recently while installing openpyxl with pip command. Then I realized this error had nothing to do with a package.
The reason of Defaulting to user installation because normal site-packages is not writeable error
If you are facing this issue that means that the Python version you are using to install the package is invalid for that package.
So make sure the pip and python versions are valid and good to go.
I was using multiple versions of Python at the same time on my machine and that was the issue.
(Nowadays Python is pre-installed with the OS and besides that, we generally install a newer version of Python as well. This is a major reason we are getting this error)
How to fix it
Well, there are multiple ways to fix this and depending upon your current version of pip and python, one of my given methods will fix this error.
If your current Python version is Python3 then run the following command:
python3 -m pip install [pacakge that you are going to install]
For example, if you are going to install opencv and then basic command is pip install opencv-python
But you should run the following command instead of that
python3 -m pip install opencv-python
It should fix your issue.
If you are using python version 2 then do the following:
python -m pip install opencv-python
To install numpy just use:
python3 -m pip install numpy
or
python -m pip install numpy
depending upon the Python version that you are using currently.
What to do if it does not work either
Just specify the exact Python version like this:
python3.7 -m pip install numpy
(If your Python version is 3.7 or change it accordingly)
Having multiple users may also cause permission issues
You can also try these:
pip install numpy --user python -m pip install numpy --user python3 -m pip install numpy --user
or
python3.7 -m pip install numpy --user
If you are using Linux then I will recommend using sudo before your command.
If you are using Windows then try to run the CMD as administrator.
Just right-click on your CMD and click run as administrator.
The last and most complicated (As well as best) method is creating a virtual env.
You can check this: Create virtual environment using venv
Description
These two errors are always prompted

Code of Conduct
- I agree to follow the PSF Code of Conduct.
In Python, the error message “Defaulting to user installation because normal site-packages is not writeable” usually appears when we try to install packages without having the necessary permissions to write to the system-wide site-packages directory.
Occurrence
This commonly occurs in virtual environments or when we lack administrative access.
Error-resolving approaches
To resolve this error, we can use the following approaches:
-
Using a virtual environment
First, create a virtual environment using tools like venv or virtualenv, using this command in the terminal:
-
Python
Когда создаю venv, и когда пытаюсь установить туда что-нибудь через pip, выходит ошибка:
Defaulting to user installation because normal site-packages is not writeableУстанавливается не в site-packages в venv как это положено, а в путь с моим пользователем в папку AppData\roaming\Python\python38

Версия питона? Версия pip’а?

Илхомжон Матазимов,
1) А в цифрах?
2) Как создавали virtual environment?
3) Вывод pip list (без venv, из активированного окружения)
4) pip list —outdated (без venv, из активированного окружения
5) requirements.txt
6) С правами на каталог/файлы все в порядке? На самом деле, это первый вопрос.
7) еще можно добавить опции —verbose и —log при запуске pip в активированном окружении.

Илхомжон Матазимов,
1) Однако, последний питон 3.8.4, но это мелочь.
2) Какая версия PyCharm? Я спрашиваю, потому-что последние версии PyCharm запрашивают адинистративные права для апдейта пакетов в директории Питона. Ну и я сам на нечто подобное недавно нарвался при обновлении Pycharm. Снес вместе с настройками, переставил и восстановил настройки синхронизацией из Jetbraon’овского облака. См. https://youtrack.jetbrains.com/issue/PY-41665 В общем, попробуйте повторить генерацию виртуального окружения, его активацию и запуск pip из командной строки. Мухи отдельно, котлеты отдельно.
6) Ну, если c командной строкой возникнет такая же проблема, то на права доступа таки придется посмотрерть. -
Andy_U, Такая же история. А как проверить права?
-
Andy_U, Дело в том, что не только именно в каком-то каталоге выходит эта ошибка, а вообще в корне. Даже без виртуального окружения
-
Илхомжон Матазимов, Без виртуального окружения — это нормально. Program Files доступны на запись только для администратора (или с elevated правами), т.е. когда вы cmd от админа запускаете.
А сами вы можете каталоги/файлы создавать, редактировать, удалять? А что у вас за антивирус стоит? Может, он запись pip’у блокирует (в песочнице его запускает)?
-
Andy_U, папки создавать/удалять/перетаскивать могу. Антивирус Windows Defender
-
Илхомжон Матазимов, Ну, пожалуй, я сдаюсь. Без физического доступа к компьютеру дальше только если сначала снести питон вместе с директорией из Program Files и потом переустановить с python.org, а если не поможет, операционную систему. Или ищите специалиста, какого-нибудь сисадмина, чтобы он физически посмотрел на ваш компьютер. а так получается удаление гланд по телефону
