undefined method `react' for #<Rails::Application::Configuration

Hi there.

I've just added the gem to my rails project and bundled. Although, I'm getting this error when trying to run the install generator. (Using ruby 2.20 and Rails 4.2.2)

@gemini-google-group Did you maybe forget to uninstall the react-rails gem?

We don't have any method called react.

When I received this message, it was because I had removed react-rails from my Gemfile but not the configuration code in config/development.rb
