我正在尝试使用带有 ruby 的启动命令提示符来使用 jekyll 和 jekyll-s3。使用时gem install jekyll-s3出现错误，提示缺少 libxml2，我应该访问http://nokogiri.org/tutorials/installing_nokogiri.html以获取安装依赖项的帮助。当我访问该页面时，它只是说我需要使用gem install nokogiri. 但是，当我这样做时，我会遇到类似的错误。
我在这里发现了一个类似的问题错误安装 Nokogiri 1.5.0 with rails 3.1.0 和 ubuntu但是，我不能使用 sudo 命令，因为我正在使用 Windows。在安装 nokogiri 的 gem devkit（windows）时，我还发现这个问题libxml2 丢失，并尝试使用问题中包含的命令，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。
我已经包含了下面安装 nokogiri 时出错的整个输出。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？
