Ruby에서 ScrAPI를 실행하는 방법은 무엇입니까?

Question

나는이 코드 rails로 scrapi를 실행하려고 해요 :

require 'rubygems' 
require 'scrapi' 
require 'tidy' 

scraper = Scraper.define do 
    process "title", :page_name => :text 
    result :page_name 
end 

uri = URI.parse("http://railscasts.com/episodes/173-screen-scraping-with-scrapi") 
p scraper.scrape(uri) 

그러나 나는 다음과 같은 오류가 발생합니다 :

DL is deprecated, please use Fiddle 
/usr/local/rvm/gems/ruby-2.0.0-p353/gems/tidy-1.1.2/lib/tidy/tidybuf.rb:5:in `<class:Tidybuf>': uninitialized constant DL::Importable (NameError)

     from scrapitest.rb:3:in `<main>' 

내가 무엇을 할 수있는 즉, 왜 누군가가 아이디어를 가지고 고쳐?

감사합니다.
