Sto cercando di rimuovere python 2.7 e sostituirlo con Python 3.6. La cosa principale che voglio fare è digitare "python" e il mio terminale usa python 3.6, ma per qualche motivo mi viene impedito di aggiornare python.
Ho installato python 3 con:
brew install python3
Di seguito sono riportati i comandi che sto eseguendo. Qualcuno potrebbe aiutarmi?
Guys-MacBook-Pro:bin guy$ python --version
Python 2.7.10
Guys-MacBook-Pro:bin guy$ python3 --version
Python 3.6.5
Guys-MacBook-Pro:bin guy$ whereis python
/usr/bin/python
