The goal of this idea is to make it easier to find out when someone has installed packages for the wrong python installation. I'm coming across quite a few StackOverflow posts and emails where beginners are using pip to install a package, but then finding they can't import it because they have multiple python installations and used the wrong pip.

For example, this guy has this problem: https://stackoverflow.com/questions/37662012/which-pip-is-with-which-python

I'd propose adding a simple line to the output of "pip install" that changes this:

user@user:~$ pip3 install pyperclip

Collecting pyperclip

Installing collected packages: pyperclip

Successfully installed pyperclip-1.6.2

...to something like this:

user@user:~$ pip3 install pyperclip

Running pip for /usr/bin/python3

Collecting pyperclip

Installing collected packages: pyperclip

Successfully installed pyperclip-1.6.2

This way, when they copy/paste their output to StackOverflow, it'll be somewhat more obvious to their helper that they used pip for the wrong python installation.

This info would also be useful for the output of "pip info", but that would break scripts that reads that output.

Any thoughts?
