Question

I am new to Ruby on Rails and I’m trying to go through a beginner’s tutorial on how to produce a basic rails application. When trying to generate a scaffold, I get the following error:

C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties-3.1.1/lib/rails/engine.rb:466:in routes': no >such file to load -- action_dispatch/routing/route_set (LoadError)

I have the Ruby 1.9.2 and Rails 3.1.1 versions installed on a PC running windows 7 64bit. The command I’m running is the following:

rails generate scaffold Scaff_test string:title

I am running this from the command prompt while being at the directory of the rails application that I have previously created. Any help would be greatly appreciated!

Answer 1

The error is related to routing. As part of generating required files, it will try to update the routes.rb ( which is under config/routes.rb ).

Please check it out if the file exists and if so check the file permission of the routes.rb
