I have pip version 19.0.3. I was prompted to update when using it to download pandas, and it seemed to fail partway through when I tried to update. Now, this error occurs whenever I try to reinstall, use pip, or even try to check what version I have. I deleted the two folders with pip, did not fix the problem. I even uninstalled python and reinstalled it to no success, I still get the same error. Any advice or solution is greatly appreciated, IT for my company was unable to provide a solution.
