Question

A VERY HAPPY AND PROSPEROUS NEW YEAR TO ALL.

I have started learning ROR and trying to create my first application with it. I am trying to use Twitter bootstrap gem. After bundle install, when i am trying to run the rails server command i am getting this error:

/var/lib/gems/1.8/gems/twitter-bootstrap-rails-2.1.9/lib/twitter/bootstrap/rails/engine.rb:3:in `require': /var/lib/gems/1.8/gems/twitter-bootstrap-rails-2.1.9/lib/twitter/bootstrap/rails/twitter-bootstrap-breadcrumbs.rb:33: syntax error, unexpected ':', expecting kEND (SyntaxError)

Can somebody please guide me what i am missing here ?

here is the stack trace of the same:

Answer 1

The problem is that you are using Ruby 1.8 while the syntax on line #33 (inside the twitter-bootstrap-rails gem) is from Ruby 1.9. They already fixed this to make it compatible on master. So possible solutions:

1. Upgrade your Ruby version to 1.9.

2. Use git version of the gem. Put this to Gemfile (modify the existing line) and run bundle install

   gem ‘twitter-bootstrap-rails’, :git => ‘git://github.com/seyhunak/twitter-bootstrap-rails.git’
