Installing via venv/pip fails with pip._vendor.packaging.version.InvalidVersion

[Massimo-B]

As dev-db/pgadmin4 got removed from Portage due to yarn issues as mentioned in https://bugs.gentoo.org/794460#c20 …
I tried following https://ogris.de/howtos/gentoo-pgadmin4.html to install via venv/pip. But it's failing due to the kernel version?

$ python3 -m venv ~/opt/pgadmin4
$ . ~/opt/pgadmin4/bin/activate
$ pip install pgadmin4

unames are free form, and expecting it not to contain -gentoo is wrong.

I've the same problem on Ubuntu 22 on MS Azure. The final line of the traceback is:

pip._vendor.packaging.version.InvalidVersion: Invalid version: '6.5.0-1025-azure'

I am told that installation works with pip version 24.0 and fails with pip 24.2.

I know that it works with setuptools >= 66, which was where semantic versioning enforcement was turned on for python packages. (Which seems somehow related to the issue.)

libera.net's #python seems to think that the problem is
https://github.com/pgadmin-org/pgadmin4/blob/master/pkg/pip/setup_pip.py#L48
and that this
python-poetry/poetry#7418
is related.

I am told that this is relevant:

This doesn't look like a pgAdmin issue. Installing with lower pip version works.

This issue should not be closed. Pgadmin should not use pip's version parsing code to parse the kernel version, since pip has specific syntax requirements for version strings. Requirements that the kernel versions do not conform to. Pip may have it's own issue, and might, possibly, make the problem go away. But that does not mean that pgadmin is calling the library appropriate for parsing kernel version strings.

pgAdmin isn't parsing any code. It might be some dependency python package.

If the issue is on pip side, please provide a installation guide via pip with a detailed description which pip-version pgAdmin depends on.

pgAdmin is released on PyPi since long and there were no issues regarding pip version. Packages like pip may release packages any time even after pgAdmin is released and break things.

Ok, beside my inofficial page I was following,
this is a bug report against https://www.pgadmin.org/download/pgadmin-4-python/ as it almost does the same like my page and is broken as well.

What can we do? Upstream bug report to pip? Downgrade pip? Is it already solved by the YunoHost-Apps/pgadmin_ynh@65b8094 above?
I just tried again and it still fails.
