BUG: 3.9-dbg - No module named '_sysconfigdata_d_linux_x86_64-linux-gnu

description

Very recently (today or 1-2 days ago), 3.9 deadsnakes debug builds on GitHub Actions for pybind11 started failing with `ModuleNotFoundError: No module named '_sysconfigdata_d_linux_x86_64-linux-gnu'.

Is this possibly related to #182? Could that have affected 3.9 by mistake?

the 3.9 builds haven't changed in over a month: https://github.com/deadsnakes/python3.9

I suspect you're running into https://github.com/pypa/setuptools/blob/main/CHANGES.rst#breaking-changes

I noticed that last night, but managed to forget about it by the morning! Thanks, I bet that's it. I'll verify, and close once I've verified (hopefully in an hour, but at least by tomorrow).

Setting SETUPTOOLS_USE_DISTUTILS=stdlib fixes it, so it's likely a setuptools bug. Thanks!
