Not sure why this started happening recently, see build log.

I get a similar error locally when trying to run from the scikit-learn root folder and cding out of it seems to fix it ...

Pyodide build passed see build log.

cc @agriyakhetarpal just because the need to cd might happen in other places with Pyodide and cibuildwheel.

I think it was needed at one point in #29791 (comment) but switching to cibuildwheel removed this need and now we need to do it again 🤷

Thanks for letting me know of this, @lesteve! I think not having to switch directories for testing was one of the standout features of cibuildwheel; would we be wrong if we were to call it a regression?

So I am not sure why this started happening to be honest, likely the dependabot PR https://github.com/scikit-learn/scikit-learn/pull/31125/files#diff-78a7bc1bdd4aae56dc69fba13e39ebb7e6e794ba5e7398020c0696f69f6758f8 a few days ago. Looks like the commit hash changed for the same cibuildwheel version 😱, I don't understand why to be honest.

In my last commit I fix the wrong commit hash for cibuildwheel 2.23.2 and it seems to work fine.

That may mean that there is a regression in cibuildwheel main not entirely sure to be honest.

Not too sure why dependabot opened a PR with the wrong commit hash, maybe there was a tag mishap on the cibuildwheel side for a small time window and we were unlucky enough that the dependabot PR was opened during this small time window.

Dependabot not using the correct hash is concerning.

I agree that the buggy dependabot update is concerning. I opened pypa/cibuildwheel#2348 to investigate what could have caused this. If the tag wasn't pushed several times we should open a follow-up issue on the dependabot repo itself.

This is a commit from the cibuildwheel 3.0 development (dependabot bug? It was week(s) after the release, and in a different branch), which changes the way it runs tests. You really should use a src folder (notice it is broken locally too!), but if you don't, you can use the new test-sources option to ensure you don't import files that should not be importable. The cd technique would not support iOS/Android, and had issues even with regular packages, and complicated running tests. You could set PYTHONSAFEPATH for Python 3.11+ (I wonder if we should do that?)

(I think this was expected, though I wasn't following this change closely.)
