Answer 1

Try updating your Ruby and/or RDiscount.

The latest RDiscount (2.0.7.3) should work on Ruby 1.9.3 or later.

Answer 2

I still cant get it work so have to use the old version.

gem install rdiscount -v=1.6.8 --platform=ruby

EDIT ON 2013 March 15th

The old gem give me other error.

I change to used

gem install RedCloth -v=4.2.9 –platform=ruby
