I'm having a hard time getting Sinatra running on my local setup, Ubuntu Karmic 9.10. The error getting thrown when I have require 'sinatra' is:

NoMethodError: undefined method `[]' for nil:NilClass
from /usr/local/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:891:in `compile'

I've tried:

  • Uninstalling/reinstalling Sinatra
  • Updating all gems
  • Ensuring all dependencies exist (rack)

Any ideas? Your time and help is greatly appreciated!
