Fixing python/pygments.rb Problem in Octopress

| Comments

After I posted my last blog post it was reported to me that my code blocks were no displaying properly. The readers were seeing an error like: "Liquid error: Could not open library ‘/usr/local/lib/libpython2.7.a’: ...".

Some googling informed me that the problem seemed to be somewhere in RubyPython. The instructions were relatively straightforward - but it wasn’t clear to me if I needed to do both of the directions.

The quick answer is yes. To fix this problem one must do the following:

  1. Make sure RubyPython is locked to 0.5.1 in the Gemfile (i.e. gem 'rubypython', '= 0.5.1'
  2. Create a file plugins/ruby_python_heroku_fix.rb with the contents: RubyPython.configure :python_exe => 'python2.6' (the filename is not actually important).
