pyenv unable to install 3.9.6 on Monterey 12.3

Question

I see this is a recurring question and there are no new comments about this. I've been trying to install python 3.9.6 using pyenv on both archs arm64 and i386 - using Rosetta2, without success. As I am pretty new at this, I was not able to identify what is wrong, and I would like to confirm this is not a bug or compatibility issue of any sort.

Does anyone can help to get this going? I really need version 3.9.6 running on monterrey OS :(

debug below and build attempt log attached

Answer 1

This might not be the ultimate answer, but I was able to overcome this issue with a patch. Source here

So, basically, we clone a repository from the python version we want to install, in this case, 3.9.6:

git clone https://github.com/python/cpython --branch v3.9.6 --single-branch

Go to directory

cd cpython

And for this part, we make the following changes on configure file.

diff --git configure configure

The interesting part here is that I had to save configure before throwing changes in the patch

git diff > python-3.9.6-m1.patch

And then had to undo the changes on configure, and save it again (all of this without committing to branch).

After that,

pyenv install 3.9.6 --patch < python-3.9.6-m1.patch

This was the only way I got to install version 3.9.6 with pyenv on a mac m1 Monterey 12.3, with Rosetta 2.

Answer 2

This worked for me on Monterey 12.6

cd ~/.pyenv/plugins/python-build && git pull
