Rubygems path bug with Ruby 1.9.0
If you ever encounter an error like the one below, it's because
gem_prelude.rb:114:in `push_gem_version_on_load_path': undefined method `<=>' for nil:NilClass (NoMethodError)
from gem_prelude.rb:8:in `gem'
from /usr/bin/haml:18:in `<main>'
It's some bug. So do this to solve it. Preferbly add it to your .profile
export GEM_HOME=/usr/lib/ruby1.9/gems/1.9.0
export GEM_PATH=$GEM_HOME:/home/singalong/.gem/ruby/1.9.0
When you use ruby 1.8, unset both GEM_HOME and GEM_PATH
Thank you!
