How do I upgrade to python 3.6.4 on macOS?
I’m trying to use python 3.6.4:
n155-p250:Desktop sahandzarrinkoub$ brew upgrade python3

Although I already have it installed, I can’t use it by typing python3
. How do I fix this? I want to remove 3.6.2 and map python3
to 3.6.4.
Solution
Since your python3
is not linked to homebrew, you should have homebrew force relink python3
:
rm /usr/local/bin/python3
brew unlink python3; brew link --overwrite python3
The link for python3
on my machine is:
/usr/local/bin/python3 -> .. /Cellar/python3/3.6.4/bin/python3
