Answer 1

Eseguire quanto segue per aggiornare setuptools sotto l'utente python:

pip install --upgrade setuptools --user python 

per qualche ragione, la le cose sono installate all'interno di OS X (e nel mio caso, sotto CentOS 7 all'interno di un contenitore Docker), il pacchetto setuptools non viene installato correttamente sotto l'utente giusto.
