ruby - Nokogiri 1.5.2 未安装在 Ubuntu 11.10 上

Question

很快，我知道一个 similar question .但是，遵循评分最高的答案是行不通的。我已经重新启动了我的系统和终端，但无济于事。

出于某种原因，Nokogiri 无法识别我安装了 libxslt1-dev，尽管我明确安装了它，包括 sudo apt-get install libxslt-dev 和sudo apt-get install libxslt1-dev。

这是输出；我还遗漏了什么吗？

$ gem install nokogiri -v '1.5.2'

编辑:仔细检查后，我意识到安装程序识别出我安装了 libxslt1-dev，但其中一项测试未通过。我是不是安装有问题？

编辑 2: 我正在尝试使用 bundle install 安装 capybara，在它的几个依赖项中，nokogiri 和 selenium-webdriver 找不到 libxslt，因此我无法使用 capybara。

编辑 3: 这是来自 mkmf.log 文件的错误消息；如果您需要其余部分，请告诉我。
