When I try to install from a .tar.gz package, while making warnings into errors:
python -W error -m pip install /some/path/nspace.pkga-0.1.0.tar.gz
I get this error:
ERROR: Exception:

DeprecationWarning: pkg_resources is deprecated as an API
pip seems to have vendored in a deprecated package. The pip code responsible is in pip/_internal/metadata/importlib/_envs.py in class Environment:
def _iter_distributions(self) -> Iterator[BaseDistribution]:
finder = _DistributionFinder()
for location in self._paths:
yield from finder.find(location)
for dist in finder.find_eggs(location):
# _emit_egg_deprecation(dist.location) # TODO: Enable this.
yield dist
# This must go last because that's how pkg_resources tie-breaks.
yield from finder.find_linked(location)
If I comment out the nested for loop (doing the find_eggs) thinks work fine: I get no error and a working package installed.
How do I monkeypatch that Environment instance from my setup.py file?
This is Python 3.11.3 (so it should be using importlib.metadata and not pkg_resources) on macOS, pip==23.1, setuptools==67.6.1
Background: I am just trying this out on an example package, the reason for this is based on a bug report for my ruamel.yaml package, where it is build in such a less forgiving environment. I could of course say don't use -W error, but I rather solve this, by not invoking the offending, unused code in the first place
There is a related discussion on pip's ticket tracker.
It seems like this issue has been solved in pip 23.1.1: "Revert pkg_resources (via setuptools) back to 65.6.3".
And pip 23.1.2 seems to vendor the new setuptools (and pkg_resources) as expected but without the deprecation warnings (see also this message).
