  If Python could not import the module virtualenvwrapper.hook_loader,
  check that virtualenvwrapper has been installed for
  VIRTUALENVWRAPPER_PYTHON=/opt/anaconda3/bin/python and that PATH is
  set properly.

  <p>However, I don't need virtualenwrapper now, and I don't know what exactly this error is trying to tell me. How can I fix this, or uninstall the wrapper?</p>
