I would guess that the poster has done some pip installs as root, but with 
$HOME still as their personal home directory, and is now doing some pip install 
stuff as themselves.

My advice would be to simply remove the .cache/pip directory.

Then in future, do your pip work from a proper login shell as whichever user.  
So either as yourself, or if you become root, do an "su -" to get a root login 
shell before proceeding.

Personally my practice is to mostly use pip only with virtualenvs, as myself.

Using pip as root tends to conflict with Python packages supplied by the OS 
vendor/supplier; better to stay out of the way of that and work as oneself on 
data the OS vendor doesn't want to own.
