pip: How to fix error 'couldnt find a setup script in xxx'

I was trying to install pip recently using easy_install when windows powershell threw back the error: couldn't find a setup script in xxx where xxx is a directory name.

A simple fix for this is to navigate to the specified folder and delete or rename any previously existing file or folder named pip. The problem is from a previously failed pip installation hence an already existing pip folder and easy_install expects to find a setup script in the folder. Failure to do so results in the error above.
I hope this helps.
