ruby-on-rails - 使用 Ruby 1.9.3 的 Windows 8 x64 上的 nokogiri gem 缺少 libxml2

Question

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

gem install nokogiri --pre 出现此错误:

    ERROR:  Error installing nokogiri:

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

我无法通过 SO/google groups/blogs/etc 找到具体的解决方案，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(

    rogram Files\PostgreSQL\9.2\bin;

我还尝试从 http://linux.softpedia.com/progDownload/libxml2-Download-162.html 下载 libxml2并将内容放入 C:\RailsInstaller\Ruby1.9.3\lib 以及 C:\RailsInstaller\DevKit\lib 但我收到了相同的错误。

tl;dr 根据我传递的选项，似乎有两个不同的错误。 parser.h 错误和 TrueClass“拆分”错误。

我也有过类似的挫败感，但我只是删除了 Ruby 2.0，以及为简化事情而安装的 DevKit。

然后我:

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

现在一切正常。
