在带有Ruby 1.9.3的Windows 8 x64上，nokogiri gem缺少libxml2

我发现搜索类似问题的是Nokogiri还没有使用Ruby 2.0的 x64支持。 然而，虽然我在Windows x64机器上，我的Ruby版本是来自railsinstaller.org的ruby 1.9.3p392（2013-02-22）[i386-mingw32]（使用Rails 3.2.13） 。 这也意味着已经安装了DevKit 。

gem install nokogiri –pre给出了这个错误：

Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb checking for libxml/parser.h... no ----- libxml2 is missing. please visit http://nokogiri.org/tutorials/installing_nokog iri.html for help with installing dependencies. ----- *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

虽然gem install nokogiri –pre –withwith xml2-lib –with-xslt-lib –platform = ruby会引发此错误：

我无法通过SO / google群组/博客/等找到任何具体的解决方案，有吗？

这是我的路径：

  PATH=C:\RailsInstaller\Git\cmd;C:\RailsInstaller\Ruby1.9.3\bin;C:\windows;C:\win dows\System32\Wbem;C:\windows\System32\WindowsPowerShell\v1.0\;C:\Program Files( x86)\Git\cmd;C:\Program Files\nodejs\;C:\cygwin\bin;C:\mingw64\x86_64-w64-mingw3 2\bin;C:\mingw64\bin;C:\Program Files (x86)\Heroku\bin;C:\Program Files (x86)\gi t\cmd;C:\Users\Joshua\AppData\Roaming\npm;C:\mingw64\x86_64-w64-mingw32\bin;C:\P rogram Files\PostgreSQL\9.2\bin; 

我也尝试从http://linux.softpedia.com/progDownload/libxml2-Download-162.html下载libxml2并将内容放在C：\ RailsInstaller \ Ruby1.9.3 \ lib以及C：\ RailsInstaller \ DevKit中\ lib但我收到了同样的错误。

tl; dr似乎有两个不同的错误，具体取决于我通过的选项。 parser.h错误和TrueClass’拆分’错误。

Answer 1

@Steve – 有一个新版本的nokogiri（1.6.2）支持x64 Ruby（这在Win7 x64 Ruby 200上适用于我）。 在撰写时，它是在预发布版中，使用以下命令安装：

  gem install nokogiri --prerelease 

Answer 2

我有类似的沮丧，但我刚刚删除了Ruby 2.0，以及我安装的DevKit以保持简单。

然后我：

• 安装1.9.3
  （ http://rubyforge.org/frs/download.php/76952/rubyinstaller-1.9.3-p429.exe ）
• DevKit（DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe）

现在一切正在发挥作用。

请确保您通过以下所有检查： https ： //github.com/oneclick/rubyinstaller/wiki/Development-Kit

以下是如何使用Chocolatey和DevKit x64安装适用于Windows 8.1 x64的Nokogiri。

刚刚遇到这个问题，看起来Nokogiri不支持64位Ruby： https ： //github.com/sparklemotion/nokogiri/issues/864解决方案似乎是使用32位Ruby，或者等到它们支持64位Ruby 。

更新：更新以反映来自@magiccrafter的评论，现在应该支持64位Ruby。
