This is a good point.  Thank you.

If I'm reading that correctly, that's the same distribution not found error.  I 
like your thought of python versus python3.  However, the PySide2 package on 
PyPI has a release for python2.  If the build system were using python2, I 
would expect it to download that and then fail.
