I encountered a similar issue with virtualenvwrapper complaining not being to find virtualenvwrapper.hook_loader. I was able to narrow down to this particular line in my .bash_profile

source /usr/local/bin/virtualenvwrapper.sh

as seen below

$ source /usr/local/bin/virtualenvwrapper.sh
/usr/local/opt/python3/bin/python3.6: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks. 

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 and that PATH is
set properly.

After some trial and error, it turns out that a reinstallation of the virtualenvwrapper package resolved it. This was a manifest of the fact that I recently upgrade python3 (from version 3.5.2 to 3.6.1) via homebrew and in turn it broke virtualenvwrapper's shell script that hardcoded references to the older version of python3 (in my case it was 3.5.2). In short, this below line should fix it (at least in my case it did).

pip3 install virtualenvwrapper
