真的很快，我知道similar question。但是，遵循最高评分的答案不起作用。我已经重新启动了我的系统和终端，但无济于事。Nokogiri 1.5.2不安装在Ubuntu 11.10上
由于某些原因，Nokogiri不承认我已安装libxslt1-dev，但我明确安装了它，均使用sudo apt-get install libxslt-dev和sudo apt-get install libxslt1-dev。
这是输出;我错过了其他什么？
$ gem install nokogiri -v '1.5.2'

编辑：经仔细检查，我认识到，安装承认我已经安装了libxslt1-dev，但它的失败的测试之一。我在安装时做了什么错误？
编辑2：我试图用bundle install安装capybara，它的几个附属中，nokogiri和selenium-webdriver找不到libxslt，因此，我不能使用capybara。
编辑3：这是mkmf.log文件中的错误消息;让我知道如果你需要其余的。

是否存在32/64位不匹配？ http://stackoverflow.com/questions/3496857/function-xsltparsestylesheetdoc-not-found-in-libxml2-so或者，也许这一个有一个答案http://stackoverflow.com/questions/1225703/cant-build-gem- native-extension-build-fails-can-you-see-why – 2012-04-13 22:04:10
@John我不这么认为; 'apt-get'总是给我正确的包到32/64位。 （我在'x86_64'上，而这个软件包是一个'amd64'软件包。）我重新安装它只是为了确保，而且我仍然遇到同样的错误。 – Edwin 2012-04-13 22:23:29
