Eb deploy error

When running eb deploy, I get the following error in the console
Traceback (most recent call last):
File “/usr/local/bin/eb”, line 5, in

raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The ‘six>=1.9.0’ distribution was not found and is required by blessed

Any ideas how to fix this error?
(I’ve tried to manually pip install six [through dependencies pre in circle.yaml)

i needed the upgrade six using pre in circle.yml from this post – Settings to deploy to AWS Elastic Beanstalk on CircleCi (EB Cli 3) · GitHub

- sudo apt-get install python-dev
- sudo easy_install --upgrade six
- sudo pip install awsebcli

the missing commands for ubuntu 14 was upgrade python-dev and easy_install --upgrade six
