Why can't asdf install a binary python package for the M1 family of processors instead of insisting on compiling from the source it pitifully fails?

[tardunge]

facing the same error, any intermediate fix/patch?

[hipertracker]

The problem was with Homebrew for Intel which I inherited after the migration from the older laptop. The solution is to completely remove Homebrew (https://stackoverflow.com/questions/65447875/how-to-uninstall-homebrew-using-an-arm-based-mac) and install it from scratch. It should install arm64/M1 version. Then install asdf and you can install Python for M1.

[tardunge]

Thanks for helping @hipertracker. My issue was due to ARCHFLAGS env set to "uname -m", which is actually creating the problem and giving the same error. Unsetting the env var in my zshrc file fixed the problem.

Yes this is a good question, does it have to build from source? I actually have the reverse problem, it is failing on Intel MacBook with no x86_64 symbols now found. But trying the uninstall now.

[hipertracker]

For Intel MBP you can force flags with the command export ARCHFLAGS="-arch x86_64" added to ~/.zshrc file (for M1 I use export ARCHFLAGS="-arch arm64")

I get a different error:

Same issue. Python 3.9 works but not 3.8.

This might help someone: https://glaucocustodio.github.io/2022/10/14/how-to-install-multiple-versions-of-python-on-apple-silicon-m1/

[jimblair]

Thanks for helping @hipertracker.....this fixed the issue for me (resetting the arch flag)....please remember to close all shells if you're editing your startup scripts (.zshrc, etc).

I wasn't able to fix this issue, therefore I opted with having python 3.10.5 on my local mac and will use venv with asdf for other versions of python i need. Will continue to look for a workaround

Hi @glaucocustodio Could you manage to make it work? I am facing the same issue
