  • Where to put *.pth files for custom Python site packages?

    From Christian Gelinek@21:1/5 to All on Tue Sep 17 03:40:01 2024
    We're using a library of our own Python modules & packages.

    The Python documentation[0] states that the search path can be extended
    via <name>.pth files which should be added to specific directories.
    While the documentation specifically mentions
    "lib/pythonX.Y/site-packages (on Unix and macOS)", I found that Debian
    seems to do this differently:

    $ python -c 'import site ; print(site.getsitepackages())' ['/usr/local/lib/python3.11/dist-packages',
    '/usr/lib/python3/dist-packages', '/usr/lib/python3.11/dist-packages']

    I.e. instead of `site-packages`, it uses `dist-packages` sub-folders.

    Given that these sub-folders are managed by Debian/`apt`, where should I
    place our custom.pth file pointing to other (network drive) folders we
    would like to include in Python's search paths?

    Thanks for your time.

    I think /usr/local is the one for you: the Debian package manager shouldn't touch it. It's at the front to allow you to override the distro's choices.

    This is actually a standard pattern in GNU flavoured Unix-ish environments.

    Cheers

    You can put .pth files in directories such as

    /usr/local/lib/python3.12/dist-packages

    (substitute the correct Python version). If you use a venv based at <venv-path>, the following directory would also work *for the venv*:

    <venv-path>/lib/python3.12/site-packages

    Alternatively, of course, you can rely on the PYTHONPATH environment
    variable.

    Regards
