Answer 1

It seems to be related to the python you are using :

The last 3 questions with an exception in the blob.colorize line were fixed by reinstalling / updating python or providing /usr/bin/env python was> = 2.5 and <3.0. The next version will contain a check for this.

Also shown in issue 2177 :

 dzaporozhets:~/projects/ → python -V Python 2.7.2+ dzaporozhets:~/projects/ → python2 -V No command 'python2' found, did you mean: 

Issue 2214 adds:

This is a problem because Python is in the process of transitioning between 2.x and 3.
The problem is that some distributions are already shipping (or are going to send Python3 by default), so relying on python on 2.x is treacherous. Therefore, I think the transition to python2 was right, because it can be fixed to work in all cases.

Python fix instructions if necessary:

 # Install Python sudo apt-get install python # Make sure that Python is 2.x (3.x is not supported at the moment) python --version # If it Python 3 you might need to install Python 2 separately sudo apt-get install python2.7 # Make sure you can access Python via `python2` python2 --version # If you get a "command not found" error create a link to the python binary sudo ln -s /usr/bin/python /usr/bin/python2
