Getting “ImportError: cannot import name check_output” (git aws.push on EB CLI)

I’ve installed and configurated AWS Elastic Beanstalk Command Line Tool on my Mac.

That’s what I have installed:

$ python --version
Python 2.7
$ ruby --version
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin10.8.0]
$ eb --version
AWS Elastic Beanstalk Command Line Interface v2.6.3

I have EB properly configured in order to use git with AWS

When I try to push a commit to AWS I am getting this error:

$ git aws.push
Traceback (most recent call last):
  File ".git/AWSDevTools/aws.elasticbeanstalk.push", line 21, in <module>
    from aws.dev_tools import * 
  File "/Applications/MAMP/htdocs/innbativel/.git/AWSDevTools/aws/", line 3, in <module>
    from subprocess import check_output
ImportError: cannot import name check_output

Does anyone have an idea why and how to fix it?

Git Baby is a git and github fan, let's start git clone.
