Installation fails due to conflicting apitaxcore version

[NeolithEra]

Hi, users are unable to run scriptax-runtime due to dependency conflict with apitaxcore package. As shown in the following full dependency graph of scriptax-runtime, scriptax-runtime requires apitaxcore ==3.0.9，while commandtax requires apitaxcore ==3.0.6.

According to pip’s “first found wins” installation strategy, apitaxcore 3.0.9 is the actually installed version. However, apitaxcore 3.0.9 does not satisfy ==3.0.6.

Suggested Solution

1. Fix your direct dependency to be apitaxcore==3.0.6 and ask your upstream project scriptax to loose the version range of apitaxcore. I have checked this revision will not affect your downstream projects now.
2. Remove your direct dependency apitaxcore and ask your upstream project scriptax to loose the version range of apitaxcore, and use apitaxcore transitively introduced by commandtax.
3. Ask your upstream project commandtax to loose the version range of apitaxcore.
