$ python -V Python 3.7.3 $ pip -V pip 19.0.3 from /usr/local/lib/python3.7/site-packages/pip (python 3.7) $ whereis pip pip: /usr/local/bin/pip2.7 /usr/local/bin/pip3.7 /usr/local/bin/pip /usr/local/bin/pip3.6
pip3.6 appeared after:
$ sudo su $ update-alternatives --install /usr/bin/python python /usr/bin/python3 1
