rails server command WINDOWS

I am completely new to ror and am following Michael Hartl's tutorial but I keep getting an error when I get to section 1.2.5. using the rails server command. When I use this command (whilst I am in my rail app directory 'first_app') I get the following error

c:\Users\rails_projects\first_app>rails server
c:/rails_projects/first_app/config/application.rb:7:in `<top (required)>': undefined method `groups' for Rails:
Module (NoMethodError)
        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.0.11/lib/rails/comma
nds.rb:28:in `require'
        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.0.11/lib/rails/comma
nds.rb:28:in `block in <top (required)>'
        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.0.11/lib/rails/comma
nds.rb:27:in `tap'
        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.0.11/lib/rails/comma
nds.rb:27:in `<top (required)>'
        from script/rails:6:in `require'
        from script/rails:6:in `<main>'

I can't figure out what went wrong, my bundle installed fine (section 1.2.4).

Solution

  • If your Gemfile is not set to use rails 3.1 or greater, try updating to 3.1.
