Python DistributionNotFound Error after installing

Question

Have tried many things, but keep getting this error after multiple attempts to update python, pip, etc. I am on OS X running 10.9.5.

CMD% eb 

Traceback (most recent call last):
  File "/usr/local/bin/eb", line 5, in <module>
    from pkg_resources import load_entry_point

pip install awsebcli

It will automatically upgrade all dependecies of awsebcli.
