在使用Ruby 1.9.3的Windows 8 x64上,nokogiri gem缺少libxml2

Question

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...

    ERROR:  Error installing nokogiri:

虽然gem install nokogiri --pre --with-xml2-lib --with-xslt-lib --platform = ruby引发了这个错误:

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

    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

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.

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

cinst libxml2

@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
