Re: [edk2-devel] Error building Python

Paulo,

I would urge you to use the minpython instead of the AppPkg python.  The minpython is a python 3 implementation vs. this 2.7 implementation. New development should not start on a version of python that is about to go officially EOL.

That being said, I have not seed that error message before. Maybe Daryl has a better starting point.
