I had the same problem as this one and spent so much time on configuring out what was wrong. And I finally found out what was wrong.

First I looked for where virtualenvwrapper folder exists. In my case /usr/local/lib/python3.7/site-packages. Inside the folder is hook_loader.py that caused the error.

Next, I used python script.

python3

import sys;print('\n'.join(sys.path))

I couldn't find the /usr/local/lib/python3.7/site-packages directory so, at last I wrote,

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.7/site-packages

to .bashrc file. Done.

Meaning of PYTHON PATH

As you can see in above link, PYTHONPATH augment the default search path for modules.
