Error installing python 3.7.6 using pyenv on new macbook pro M1 in OS 12.3+

I am struggling to install python version 3.7.6 using pyenv on my new macbook pro M1 running on mac os 12.3.1.

My configuration

$ clang -v

Target: arm64-apple-darwin21.4.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

$ pyenv install 3.7.6

Solution

  • Finally this patch works in installing 3.7.6 on macbook m1 using pyenv.

    To install python 3.7.6 version in mac os 12+ , M1 chip, apple clang version 13+ using pyenv, create a file anywhere in your local and call it python-3.7.6-m1.patch and copy the contents(below) to that file and save it.

    NOW we can Install python 3.7.6 using pyenv as follows (need to be in the same directory as the patch file that we just created):

    pyenv install --patch 3.7.6 < python-3.7.6-m1.patch

    To install other python version on mac os 12+ , M1 chip, apple clang version 13+ using pyenv (not tested but should work)

    Shallow clone the branch of python version you are interested in installing. go to https://github.com/python/cpython and find the versions available for cloning under "tags" dropdown

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

    Now make changes to the two files in it (configure.ac and configure). the git diff should look like the one shown above. The line numbers will be different based on which version of python you are installing, this git diff file is for 3.7.6 and can't be directly used for other versions. for other versions of python, search for the exact line of code being edited/deleted in the exact file as shown in the above git diff and make the changes accordingly. then save the git diff in a new file as follows.

    git diff > python-3.x.x-m1.patch

    Now we can install that version using:

    pyenv install --patch 3.x.x < python-3.x.x-m1.patch
