Injecting VCS URL of package that is already installed does not install proper version

[aereaux]

Describe the bug

I am trying to install the version of gajim from git, which requires the version of python-nbxmpp from git. When I run the inject command it runs fine, but doesn't install the proper version.

When I run pipx runpip gajim install git+https://dev.gajim.org/gajim/python-nbxmpp/ --force-reinstall it seems to do what I need, so maybe a --force-reinstall or something is needed?

How to reproduce

$ pipx install git+https://dev.gajim.org/gajim/gajim/
  installed package gajim 1.9.3, installed using Python 3.12.6
  These apps are now globally available
    - gajim

Expected behavior

The pip freeze command should show the git version of nbxmpp.

Hi @aereaux, seems the problem is caused by the ambigious configuration of nbxmpp. As it is shown here, the package version is set as the attribute value of nbxmpp.__version__ and it is always 5.0.3 for all the commits between 5.0.3 and 5.0.4. So I suppose you might need to integrate with setuptools-scm to make it work as expected. Would you like to have a try on it?

Actually, I tried to reproduce the issue by using another Python package repo with setuptools-scm integration and it works as expected.
