Cannot load underlying module for 'Darwin

[Aurther-Nadeem]

I believe this may be happening due to me using Apple Silicon, but I get this error when running:
import PythonKit

error: could not find module 'PythonKit' for target 'arm64-apple-macos'; found: x86_64

I've tried running with arch -x86-64 but it then says error: cannot load underlying module for 'Darwin'

Any way around this?
