Stumbled too many times to get this to work.

Errors and resolutions:

Error:

-bash: /usr/local/bin/python: No such file or directory

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/python and that PATH is

set properly.

Resolution:

Add the following line to the ~/.bash_profile file:

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3

In a MAC, the default path /usr/bin/python is the one that is used by the system installation. For Python installed using brew, the path is /usr/local/bin/python
