BUG: Cannot install SciPy 1.9.3 in Python 3.10 in macOS

Question

Tried to install SciPy from the terminal using pip and from the idle using Github, but none of it worked.

In the documentation it says that it should support Python 3.10, so I do not know the reason of the issue.

Every other package, I have had no issue to install.

Any ideas about how to solve?

This is the error shown:

I'm guessing you're on macOS 11 with M1? (Please always give the OS and version as part of a question). If so, then scipy doesn't make wheels for macOS11 + M1, there are a few bugs that can't be removed. I advise upgrading to macOS 12 in this situation.
