Jekyll, Pygments and pygments.rb

Question

I'm getting the following error when I try to run jekyll serve, but the error doesn't happen when I run Jekyll locally:

Does anyone know how to fix this?

perhaps you wrote a post titled: 2010-04-09-python-and-sqlite.textile? The error says it can't find the header information... did you accidentally delete it? I would start there.

It works fine locally with the exact same gems, so the post itself isn't the problem.

Personally, I would remove that post and see what happens.

I just googled and found this... http://www.wongdev.com/blog/2013/01/16/octopress-on-archlinux/

at the bottom: Liquid Exception: Failed to get header. in 2013-01-16-octopress-on-archlinux.markdown This is caused by Python 3 being unsupported by the pygments.rb gem. The gem calls Python via #!/usr/bin/env python. In Arch Linux, python defaults to Python 3.x and python2 to Python 2.x.

You may need to activate a virtualenv and generate the blog with it.
