  • pip install --user broken in debian testing?

    From Barry Scott@21:1/5 to All on Sun Feb 26 11:10:01 2023
    I have been using the following to add useful python based commands to
    my user locally:

    $ python3 -m pip install --user <package>

    For install I get this:

    $ python3 -m pip install --user colour-text
    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.

    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.

    This look wrong to me as I am not installing into the systems site-packages.

    That's the new intended behavior. I you want non-debian python packages, install them in a non-debian python via virtual environments.

    You can read the idea in the document that was linked in the message you
    got.
    To quote it, "This applies both to system-wide installs (sudo pip install)
    as well as user home directory installs (pip install --user), since
    packages in either location show up on the sys.path of /usr/bin/python3."

    Please aso note that debian-mentors@ is not a support channel, that would
    be debian-user@.

    According to the PEP it's both, and it actually makes sense. Python does not distinguish between packages in system-wide and user-specific locations.

    Allowing non-virtualized installation of Python packages into the user-specific location could therefore break Python programs and libraries installed by apt/dpkg.

    Virtualized installations do not cause issues and are still allowed using, for example, pipx or raw venvs.

    I think this is a major bug.

    This is the new standard for Python which Debian respects it too.

    If I may make an observation, how would one implement these venvs properly then if something requires to be launchdd via systemd (custom services)? Or specialized daemons which do not properly behave as expected in venvs?

    This is going to increase complexity massovely for end users who expect userspace module installation to work. Was this decision a Debian level decision or an upstream Python decision?

    According to the PEP it's both, and it actually makes sense. Python does not distinguish between packages in system-wide and user-specific locations.



    Allowing non-virtualized installation of Python packages into the user-specific location could therefore break Python programs and libraries installed by apt/dpkg.

    On Fedora they use the -s option for all system apps that use python to prevent breakage from user installed packages.

    I have been living in that happy world where pip install --user was safe to use.


    Virtualized installations do not cause issues and are still allowed using, for example, pipx or raw venvs.

    I am aware of that, but don't reach for venv for simple stuff.
    Clearly I'm going to have to figure out how to do this for my use case now.

    I think this is a major bug.

    I have been using the following to add useful python based commands to my user locally:

    $ python3 -m pip install --user <package>

    For install I get this:

    $ python3 -m pip install --user colour-text
    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.

    This look wrong to me as I am not installing into the systems site-packages.
