Title Body

I'm new to Rails and am currently working through a guide. The guide states: Use a text editor to update the Gemfile needed by Bundler with the contents of Listing 2.1. source 'https://rubygems.org' gem 'rails', '3.2.3' group :development do gem 'sqlite3', '1.3.5' end # Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', '3.2.4' gem 'coffee-rails', '3.2.2' gem 'uglifier', '1.2.3' end gem 'jquery-rails', '2.0.0' group :production do gem 'pg', '0.12.2' end We then install and include the gems using the bundle install command: $ bundle install --without production If Bundler complains about no such file to load -- readline (LoadError) try adding gem ’rb-readline’ to your Gemfile.) I followed the steps even adding on gem 'rb-readline' to the Gemfile , but apparently the file can't be found and when I go to my text editor I do see the Gemfile itself. I noticed that they made me put gem 'rails', 3.2.3 and my version of Rails is 3.2.1 so I tried changing it to 3.2.1 but that didn't work either. Any thoughts or advice would be much appreciated.
