Thank you!

The failing test seems to be happening now regardless of this change: https://github.com/pypa/setuptools/actions/runs/12298183072/job/34321035714#step:3:49.

I don't know if anything changed in the latest versions of Python being distributed to macOS, so that __file__ is no longer available on the scope.

Aha, that's a different failure actually, setuptools/tests/test_easy_install.py::TestSetupRequires::test_setup_requires_override_nspkg is the test that is legitimately failing and would need to be updated here.

setuptools/tests/test_easy_install.py::TestSetupRequires::test_setup_requires_override_nspkg is the test that is legitimately failing and would need to be updated here.

This looks like it is checking deprecated functionality? Not sure we have to account such an edge case since we are moving away from easy_install. Maybe we can do a major bump to show that the change may be considered a breaking change.

I'm not sure! I think the test is just broken in a way I haven't been able to figure out (it mixes the distribution name and the namespace name as one thing in the helper functions) but I think the underlying functionality probably still works?
