I am getting

```
$ rake routes
rake aborted!
ArgumentError: Missing :action key on routes definition, please check your routes.
/usr/local/rvm/gems/ruby-2.1.2/gems/actionpack-4.1.5/lib/action_dispatch/routing/mapper.rb:243:in `default_controller_and_action'

```

Here is my Routes.rb

```
Rails.application.routes.draw do
  get 'script/index'

  get 'landing/index'

  root 'landing/index'
end

```

What is causing the problem and how do I fix it.
