undefined method `cache_sweeper'

[ari]

I'm trying to call the annotate gem in order to update the documentation in the model. But I get this error:

NoMethodError: undefined method `cache_sweeper' for TagsController:Class

@ari I couldn't reproduce it. I execute two commands rails g annotate:install and take annotate models. And both of them passed successful.
