After Deleting some Python Files, I can't install pytorch any more via pip
Unfortunately I deleted some files of Python. I got macOS Catalina and I want to install pytorch with the command: 

pip3 install torch


If I enter this in my terminal I'll get


  Building wheel for torch (setup.py) ... error

Is there a way to solve this problem? Do you need further Information?

UPDATE

I changed the way of the enviroment (without anaconda) and so I get this error message:

Try running:

pip3 install --upgrade --force-reinstall pip


If that doesn't work you can always try reinstalling python from https://www.python.org/downloads
