I also got this error and a couple of other similar errors, and finally got a solution: you need to have a couple of compatible versions of the required Ruby, Python and Pygments.
Hope this helps.
Edited: Remember to add the correct PATH to the system variables. In my case, it was:
C: \ python27; C: \ Ruby193
To improve this content, there is a simple tutorial (written in Portuguese, but I think you can understand the steps, always considering the software / plugin versions listed above) - view the tutorial .
