How to install a Python 3 package, system wide, using pip?

Question

I don't want to use virtualenv. I want to install system wide, as root.

How do I make pip install a package for Python 3?

If I simply do

pip install <package name>

It installs it for Python 2.

This is specifically what happens for chatterbot when I do:

pip install chatterbot

As root.

How do I make it install chatterbot for Python 3?
