Rails make a gem via engines

I want to make a gem which contains a view helper. I watch this tutorial, but I encounter some problems.

Here is github if you need more information.

The helper would only print Hello world!.

app/helpers/google_code.rb

module GoogleCode
    def self.put_code
        content_tag(:p, "Hello world!")
    end
end

lib/google_prettify_rails.rb require "google_prettify_rails/version"

module GooglePrettifyRails
    class Engine < ::Rails::Engine
    end
end

Then, I created another project and installed it, and I type <%= put_code %> in view. However, it threw this error 

Couldn't find GooglePrettifyRailsHelper, expected it to be defined in helpers/google_prettify_rails_helper.rb

The name of your helper and the name of the file the helper is in do not match. Just change first line of app/helpers/google_prettify_rails_helper.rb to GooglePrettifyRailsHelper.
