No module named '_ctypes' error for Python 3.7 with Mac Pro M1

[JIAZHEN]

Hi,

I installed python 3.7.12 with asdf. Then do pip3 install ansible throws error

Is it a known issue with asdf python 3.7?

I'm seeing this on M1 as well, with other dependencies. The specific dependency it's failing to install at the moment is ruamel.yaml.clib and I've seen it with others.

(Also, for completeness I should note I did not install Python 3.7 on my M1 via asdf; I just found your issue here while searching for solutions.)

I'm having the same issue with python3.7 + asdf, but no Manjaro Linux

Same issue here, python 3.9 and also 3.11 + asdf and Ubuntu.
