What version of Python and Zope/Addons I am using:

3.10.4

I have no M1 so I can just guess: There are no specific wheels for M1 processors of BTrees released,` yet. There is not even a universal wheel. So it has to be compiled from the sources.

• Do you have a compiler chain (Xcode.app) installed?
• Which version of pip are you using? (Call pip --version)
• What happens if you install persistent the package first:
  • This is the package needed for BTrees where it breaks in your traceback.
  • Call: pip install persistent BTrees
• The end of the traceback says: (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')) – Did you upgrade your computer keeping the hard drive contents? It seems you have to do a clean install – whatever this means.

This should be solved now as there are M1 wheels.
