Question

我尝试使用以下代码rails运行scrapi：

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)

但是我收到以下错误：

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>'

有人知道为什么会这样，我该怎么做才能解决它？

谢谢。

请尝试使用http://github.com/libc/tidy_ffi。似乎tidy gem不再维护了。

如何用Ruby运行ScrAPI？
