I ran into this as well, but was able to solve it by reinstalling Python after installing xz via Homebrew. Not sure what to do if you're not using Homebrew.

I'm seeing the same issue, but I primarily manage packages with Nix via nix-darwin; no Homebrew installed. I added the xz package via Nix but asdf doesn't seem to know where it is.

For Linux (tested with Ubuntu 22.04), you need the following dependencies for asdf-python: libsqlite3-dev libbz2-dev liblzma-dev libffi-dev

I think some form of tkinter or tcl is also required if you develop GUI apps.

On Mac Homebrew provides xz this is a newer algorithm implementation which has lzma backward compatibility. xz on Linux, NixOs and nix-darwin should also do the same.

Also on Mac libffi installation seems to be only required for very old versions of python , newer versions seem to have patches applied around ctypes by python-build which is used under pyenv which inturn is used by asdf-paython.

on a brand new computer (ubuntu 22) I forgot what dependencies I needed for Python via ASDF, it would be nice to have it in the README wdyt ?

There is a link in README.md with a link to system build dependencies which covers the various requirements for platforms.
