using pip3 to call pip

[Russell Jones]

Could you try "which -a pip3" and "which -a pip-3.6"?

You may need to use something like

alias pip3=pip-3.6

or the more recently preferred "python3 -m pip" 
https://docs.python.org/3.6/installing/ ( though these docs are a bit 
inconsistent with https://www.python.org/dev/peps/pep-0394/ )
