I had the exact same error message. Ray Donnelly at Continuum Analytics Support Group provided the following solution, which resolved the issue for me:

When you pip installed virtualenvwrapper, pip will have installed virtualenv for you as it is a dependency. Unfortunately, that virtualenv is not compatible with Anaconda Python. Fortunately, the Anaconda Distribution has a virtualenv that is compatible. To fix this:

pip uninstall virtualenv
conda install virtualenv

can't get virtualenv to work with anaconda3 v4.3 on mac
