this problem has troubled me for a long time, can you give me some help or advice

Per scikit-build/scikit-build#531 (comment), could you try to delete _skbuild folder?

[hu-hamster]

After I delete the _skbuild directory, the error message is still the same.

You may need to remove other temporary files, such as _cmake_test_compile that I can found in your output.
