I followed online instructions on how to install pip
on macOS (for example this, this, and this).
I all seems to simple, but it\'s not working for me.
Use brew for Macs
brew install python
this will come with pip and both python2 and python3
instructions to bypass 2 python versions (if you want) are at https://pip.readthedocs.io/en/stable/installing/
otherwise, it'll just be "python3 <'program'>"
