Expanding upon zzheng's explanation, if you're still having issues try running gem list.
Then make sure pygments.rb (0.5.2) isn't installed. If it is, just run this command.

That should take care of your problem, and you should be able to publish with Jekyll happily on Windows once again.
EDIT: Also, based upon my own experience, this may cause another error. Liquid Error: Failed to get header. in 2013-07-20-post-name-here.md. The (unconfirmed) solution is to install Python 2.7.* if you have not already done so, although some people report that this does not fix the problem.
