Can anyone point me to why this error keeps showing up during circleci testing?

Neither Pillow nor PIL could be imported: No module named Image python
  manage.py test returned exit code 1

For the record, I followed every resource I had in terms of installation instructions for pillow.  
Can anyone PLEASE help me?  I'm getting desperate.
Have you specified the Python version in your circle.yml? If Python version is not specified, the virtualenv might not get created for you.
