Damn it! :)

Pip3 is usually a sign that you're installing into your system python packages instead of a virtualenv. The usual best practice is to use a virtualenv.

I'm not sure how that is good practice?

Its a Python3 script, shouldn't it use pip3 ?

  I installed it with: $ sudo pip3 install litecli

  (seemed to work)

Dont use sudo pip, it can break your system.

It's compatible with python2

Please don't. That's the sort of name that makes it impossible to talk about the project, let alone use it at work.
