Ruby 1.9.2与Windows上的scrubyt

Question

在Windows上使用Ruby1.9.2时，在调用Scrubyt::Extractor.define do时会出现以下错误

C:/Ruby192/lib/ruby/gems/1.9.1/gems/activesupport-3.0.9/lib/active_support/dependencies.rb:479:in load_missing_constant': Scrubyt::Navigation is not missing constant Mechanize! (ArgumentError)

尽管在文件中指定了“要求‘机械化’”，但没有加载机械化，这似乎与@@agent = Mechanize::Mechanize.new /core/navigation/agents/ Mechanize ize.rb中的核心有关

我安装了mechanize (2.0.1)，hpricot (0.8.4)，fireawtir (1.9.3)和nokogiri (1.5.0)

你知道为什么会出现这个问题吗？

Answer 1

现在通过使用mechanize (0.9.3)解决，并将scrubyt-0.4.31\lib\scrubyt\core\navigation\agents\mechanize.rb，@@agent = Mechanize::Mechanize.new更改为@@agent = WWW::Mechanize.new。可能只是我自己的一个问题，但在这里发布解决方案，以防其他人可以使用它……
