安装nokogiri时出错

Question

我想用ruby启动命令提示符来使用jekyll和jekyll-s3。当使用gem install jekyll-s3时，我得到一个错误，告诉libxml2丢失，我应该访问http://nokogiri.org/tutorials/installing_nokogiri.html以获取安装依赖关系的帮助。当我访问该页面时，只是说我需要使用gem install nokogiri。但是，当我这样做时，我收到了类似的错误。

我发现一个相似的问题在这里问Error installing Nokogiri 1.5.0 with rails 3.1.0 and ubuntu，因为我使用Windows，我不能使用sudo命令。我还发现这个问题libxml2 missing when installing nokogiri's gem devkit (windows)，并试图使用包含在问题中的命令，并且我得到了问题中包含的相同错误输出。那里的评论似乎没有帮助。

我已经包括在下面安装引入nokogiri错误的整个输出。我猜我需要安装某种先决条件包/库，但我不知道如何。我应该怎么做才能让这些宝石正常工作？

我不认为在Windows上支持Ruby 2.0.0和x64的nokogiri还支持。我有类似的问题。
