title: Python pip install ends with "command errored out with exit status 1:..."
body: <p>I'm new to python, and I'm trying to run some basic codes that require some libraries.
  And when I'm trying to install a library (e.g. pip install matplotlib-venn) I get this long error:</p>

  <p>I tried to reinstall python multiple times (I'm using the latest version 3.9).
  I updated the path variables as I've seen in other posts.
  I tried to run the same command but with pip3, same thing.</p>
