Modules issue, pip3 download modules only to pyhton3.5.2 not the latest 3.6.1

There is a different site-packages directory for each version of Python that you have. If you do pip3 install pyperclip it will only install it in the site-packages for version aliased as python3.  If you use pip3.6 install pyperclip , it will install in site-packages for v3.6.  This also applies with removing, upgrading and listing modules for the various versions.

I don't have the Linux machine running, but it's possible that "pip" and "pip3" will work with both Python 2 and Python 3.

EDIT:
If you are on a Linux machine I would highly recommend you not mess with the defaults, as Linux, especially the desktop environments use a great deal of Python code.  Also, when you install a new version (as in 3.6.1) it is usually in a directory different from the two default versions (usually the"/opt" directory). Another thing to keep in mind, is the "shebang line", with the default versions, it is usually #! /usr/bin/env python or #! /usr/bin/env python3 , with self installed versions, that may change to something like #! /usr/local/bin/python3.6
