Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'C:\Python27\python.exe'.



Collecting pip==8.1.2

You are using pip version 7.1.0, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
