I have 3 python versions installed: default mac python 2.7, brew python2.7 and brew python3, but my pip libraries are not being linked to anyone.
user$ which python
/usr/bin/python
user$ which python2.7
/usr/bin/python2.7
user$ which python3
/usr/local/bin/python3
user$ which pip
/usr/local/bin/pip
user$ which pip2
/usr/local/bin/pip2
How can I link the pip installed libraries to python and python2.7 commands?
