Trying to install via homebrew. The weird thing is that I can install pyenv 3.9.6. I think it has something to do with that version not being compatible with the new silicon M1 chip. I've tried Problems installing python 3.6 with pyenv on Mac OS Big Sur and Issues Installing Python 3.x via Pyenv but nothing is working. Thanks in advance!!

Answer 1

https://www.python.org/downloads/release/python-391/

3.9.1 is the first version of Python to support macOS 11 Big Sur.

https://www.python.org/downloads/release/python-3810/

Python 3.8.10

... But there's a bunch of important updates here regardless, the biggest being Big Sur and Apple Silicon build support.

You cannot install 3.8.5, unfortunately.

I solved my issue of installing 3.7.6 using pyenv on macbook m1 using this solution. This also shows how to create a patch file that should help install other python versions. hope this helps.
