As long as pip lives within the scripts folder you can run

python -m pip ....

This will tell python to get pip from inside the scripts folder. This is also a good way to have both python2.7 and pyhton3.5 on you computer and have them in different locations. I currently have both python2 and pyhton3 installed on windows. When I type python it defaults to python2. But if I type python3 I can use python3. (I also had to change the python.exe file for python3 to "python3.exe")If I need to install flask for python 2 I can run

python -m pip install flask

and it will be installed in the pyhton2 folder, but if I need flask for python 3 I run:

python3 -m pip install flask

and I now have it in the python3 folder

On Windows, pip lives in C:\[pythondir]\scripts.

So you'll need to add that to your system path in order to run it from the command prompt. You could alternatively cd into that directory each time, but that's a hassle.

See the top answer here for info on how to do that: Adding Python Path on Windows 7

Also, that is a terrifying way to install pip. Grab it from Christophe Gohlke. Grab everything else from there for that matter. http://www.lfd.uci.edu/~gohlke/pythonlibs/

I found this much simpler. Simply type this into the terminal:
