image not found error when attempting to import pyxel on mac
Was able to install successfully pyxel after updating my python version.

However now am unable to import pyxel in my python code, or attempt to run any of the examples.
I Am on Mac OS Catalina & the latest python version

I get the following error when attempting to load/import pyxel.
