我对 NewsTrust 的 SocialNews 框架有疑问。我在 Windows XP 上使用 Ruby 187、Rails 2.3.11、DevKit、Visual C++ 2008 EE，当我运行ruby 脚本/服务器时出现以下错误： http: //pastebin.com/LpNDRqcg。宝石文件：

group :development do
# bundler requires these gems in development
# gem "rails-footnotes"
end
group :test do
# bundler requires these gems while running tests
# gem "rspec"

end
有人可以帮我吗？我需要做什么？无论如何，谢谢..顺便说一句，如何从这个脚本（SocialNews 框架）将 ImageScience 转换为 Rmagick？
