Using sudo with pip3?

[Clint Moyer]

I would lightly advise against, assuming both Pip and your package
manager are trying to accomplish nearly the same thing. Stick with
updating through the repo.

If you find that the version your OS provides is out-of-date compared
to what's on PyPi or Github, then you might want to remove from your
OS and re-install through Pip, for those discrete cases. That's the
platform agnostic route.
