Is Python 3.12 different? about cibuildwheel

[Czaki]

Python 3.12 has removed deprecated API from importlib module here: python/cpython#98040

As You do not provide source code we cannot check where is a problem. The latest setuptools is ready on python 3.12

Thanks. I appreciate that lack of source code makes this more difficult to debug. I updated the requirements.txt file to rely on the most recent setuptools. I don't see any references to, for example, pkgutil in our code base so I'm still quite confused.

Did you have pyproject.toml file with build-system.requires section? Maybe you pin setuptools there?

Also, older versions of pretty much everything might trigger this. NumPy, for example, must be 1.26.0+ or you'll see this sort of problem. If you are pinning or limiting at all, most likely in pyproject.toml or in requirements.txt if you install from there before building (and avoid build isolation). I'd recommend fully regenerating requirements.txt from requirements.in on Python 3.12 if that's the case.

Thank you. It was a bad version in pyproject.toml. blush.
