The oficial documentation can be found here.

How do I solve "error: externally-managed-environment" everytime I use pip3? – Debian

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.

See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing –break-system-packages.
hint: See PEP 668 for the detailed specification.

I use apt upgrade and update.

    You can use python venv like described here.

    However if you really want to install packages that way, then there are couple solutions:

    • remove file /usr/lib/python3.x/EXTERNALLY-MANAGED,
    • use pip‘s argument --break-system-packages,
    • add following lines to ~/.config/pip/pip.conf:
    [global]
break-system-packages = true

    that issue from pip just run the command and it will downgrade it.

    => pip install pip==22.3.1 –break-system-packages

    surely that will help.

    To fix that error you can use a python virtual environment. Here is how you can do that.

    Install python virtual environment
    Then you can move into a directory that you wish and create a virtual environment using virtual env your_folder_name
    While in the environment you have created type source bin/activate
    Here is an easy way (video)
    Then that is it

    I installed pipx first:

    apt install pipx

    Then I used pipx to install radian:

    pipx install radian

    Later to confirm the installation location (in my case to configure VSCode) I ran:

    pipx list

    Happens to me after I changed the name of the folder containing my virtual environment
    If you want to rename a virtual environment, changing the name of the folder doesn’t work, what I did was re-creating it
