chore: nox error "ModuleNotFoundError: No module named 'pkg_resources'"

[smarie]

setuptools v82 does not include pkg_resources anymore but somehow it is needed somewhere in the wheel building process.

nox > python -m pip install . --no-deps

  note: This error originates from a subprocess, and is likely not a problem with pip.

[notice] A new release of pip is available: 25.1.1 -> 26.0.1
[notice] To update, run: python.EXE -m pip install --upgrade pip

See above for output.

One way to fix is to limit the setuptools version. Maybe upgrading pip could also solve this, but I am not certain.

Our build system really needs to be updated...
