how to fix " Could not find a version that satisfies the requirement install (from versions: ) No matching distribution found for install " error

I want to install tweepy module to my python project. I read in documentation to use command "pip install tweepy". But it shows up an error in command prompt.

C:\Python36>pip install tweepy
Collecting install
  Could not find a version that satisfies the requirement install (from versions: )
No matching distribution found for install

Edit-1

I tried to install python-twitter module and the same error shows up.

C:\Python36>pip install python-twitter -v

Solution

Tried different ways like pip3 install tweepy and pip tweepy like the solution advised above but that didn't work. Tried upgrading and reinstalling pip but still no solution. Had to do a whole reinstallation of python environment.
