keybounceMBP:js-beautify michael$ port select pip pip36
Selecting 'pip36' for 'pip' failed: could not create new link "/opt/local/bin/pip" pointing to "/opt/local/Library/Frameworks/Python.framework/Versions/3.6/bin/pip": permission denied
keybounceMBP:js-beautify michael$ sudo !!
sudo port select pip pip36
Selecting 'pip36' for 'pip' succeeded. 'pip36' is now active.
While installing pip36 does result in "port select --summary" showing that it is active, it actually is NOT until you run the port select command. Odd.
(Equally odd -- installing python36 in the first place did not install a pip if it is part of the python system).
Side question: Why is there not just a "python3", why do we have to specifically select one of several versions?
