This one will solve all your problems not only on Mac but
to find it on Linux also ( & every basic shell).
TL;DR (you don’t have to go through all the answer – just the 1st half).
LET’S GO
Run in terminal:
which python3
On Mac you should get:
/usr/local/bin/python3
WAIT!!! This is prob a symbolic link, how do you know? Run:
ls -al /usr/local/bin/python3
and you’ll get (if you’ve installed Python w/ Brew):
/usr/local/bin/python3 -> /usr/local/Cellar/python/3.6.4_4/bin/python3
which means that your
/usr/local/bin/python3
is actually pointing to (the real location)
/usr/local/Cellar/python/3.6.4_4/bin/python3
That’s it!
Longer version (optional):
If for some reason, your
/usr/local/bin/python3
is not pointing to the place you want, which in our case:
/usr/local/Cellar/python/3.6.4_4/bin/python3
just back it up (+cool trick to add .orig suffix to file):
cp /usr/local/bin/python3{,.orig}
and run:
rm -rf /usr/local/bin/python3
now create a new symbolic link:
ln -s /usr/local/Cellar/python/3.6.4_4/bin/python3 /usr/local/bin/python3
and now your
/usr/local/bin/python3
is pointing to
/usr/local/Cellar/python/3.6.4_4/bin/python3
Check it out by running:
ls -al /usr/local/bin/python3
