asdf plugins affected (if relevant)

No response

I can gather 2 pieces of information from your initial error:

Point 2 sounds like a missing system dependency. asdf doesn't manage dependencies, you have to follow instructions from the plugin repo for dependencies.

A quick Google of point 2s error returns this SO Q.&A . The result of which is you need a new system dependency libbz2-dev . This lib is mentioned in #570 and as stated there, is not an issue with asdf , but that a Python lib you are using requires a system dependency you are missing.

I am closing this as the method to "install python normally" that "operate optimally" likely installs this system dependency for you that were not manually installed during the asdf-python install.

asdf-python uses python-build which in turn is a pyenv plugin which itself suggests installing common system libraries Python libraries use. This pyenv list of tools is shared in #570 .
