我还尝试从C:\RailsInstaller\Ruby1.9.3\lib以及C:\RailsInstaller\DevKit\lib下载libxml2并将其内容放入其中，但我收到了相同的错误

tl；根据我传递的选项，似乎有两种不同的错误。parser.h错误和TrueClass“split”错误。

我也有类似的挫折感，但我只是删除了Ruby 2.0和我安装的DevKit，以保持简单

然后我：

已安装1.9.3
（）
DevKit（DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe）

现在一切都在运转

请务必在以下地点完成所有检查：我自己也遇到了这个问题，看起来Nokogiri不支持64位Ruby：解决方案似乎是使用32位Ruby，或者等到他们支持64位Ruby

更新：更新以反映@magiccrafter关于64位Ruby现在应该得到支持的评论。

以下是如何安装Nokogiri for Windows 8.1 x64 with Chocolate和DevKit x64

gem安装nokogiri--with-xml2-include=C:\chocolate\lib\libxml2.2.7.8.7\build\native\include--with-xml2-lib=C:\chocolate\lib\libxml2.redist.2.7.8.7\build\native\bin\v110\x64\Release\dynamic\cdecl--with-iconv include=C:\chocolate\lib\lib\libiconv.1.14.0.11\build\native\include--iconv lib=C:\chocolate\lib\libiconv.redist.1.14.0.11\build\native\bin\v110\x64\Release\dynamic\cdecl——xslt include=C:\chocolate\lib\libxslt.1.1.28.0\build\native\native\include——xslt lib=C:\chocolate\lib\libxslt.redist.1.1.1.1.28.0\build\native\bin\v110\x64\Release\dynamic

@Steve-有一个支持x64Ruby的应用程序（这对我在Win7x64Ruby200上很有用）。在编写本文时，它处于预发布状态，请使用以下方式安装：

 gem install nokogiri --prerelease

谢谢，我也做了类似的事情。最后，我删除了所有与ruby和rails相关的内容，并从railsinstaller.org进行了新的安装。电线在某个地方交叉了，但现在似乎在工作。不再相关了。已实施支助。
