Can't run this open source project http://railsapps.github.com/tutorial-rails-bootstrap-devise-cancan.html.I'm using Ruby version1.9.3p286 and Rails 3.2.8. I've installed all gems successfully, but when trying to run from RubyMine output the following:

It can't find the diff-lcs-1.1.3 gem, try running bundle install or installing the gem manually.

EDIT: seeing your gem file, it's missing 

gem "diff-lcs", "1.1.3"

little addition to @Baboon's solution, try to remove Gem.lock file and run bundle install again

How ever, once you are comfortable with the example, You might be interested in "rails composer" to generate your rails skeleton

  • tried to remove gem.lock file and run bundle install but it couldn't help me, thank you for rails composer! – Aydar Omurbekov Nov 05 '12 at 11:15
  • Good advice from @sameera207. Use Rails Composer to generate the app. And read this article from the author on Installing Rails: http://railsapps.github.com/installing-rails.html – Daniel Kehoe Nov 06 '12 at 00:34
