无法在 Windows 中安装 Nokogiri for Ruby



我知道这很简单，但我就是想不通。我需要用Ruby运行一个脚本，它需要Nokogiri。我确实在其他语言方面有一些经验，但在Ruby方面没有。

这是我的系统：

Ruby 2.0.0-p195（x64）已安装在C:\Programs\RubyLanguage

Ruby开发工具包（mingw64-64-4.7.2-20130224-1432）安装在C:\Programs\RubyDevKit

当我运行gem install nokogiri时，我得到这个错误：

    ERROR:  Error installing nokogiri:
        The 'nokogiri' native gem requires installed build tools.
Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'

很简单。所以我按照上面的链接做了第3步。然而，步骤4表示生成"；配置yml"；。我照做了。现在，该文件是一个包含一些注释的空列表。由于上面的错误，我仍然无法安装Nokogiri，而且我似乎无法使用DevKit。我想说的是，安装开发工具包的步骤对我来说还不够清楚

更新它现在说Nokogiri的安装失败（DevKit根据步骤5工作：安装json-1.8.0的文档安装了1颗宝石）

更新：从1.6.2版本开始，Nokogiri现在支持Ruby 2.0.0的64位版本。（注意，它需要libxml>=2.6.21）

如果您出于某种原因仍然需要安装x86版本，或者如果您想了解如何使用DevKit安装和构建gem:，答案如下

Nokogiri还不支持Ruby 2.0.0的64位版本。您可以在此处阅读并关注状态。

但是Nokogiri确实支持x86版本的ruby 2.0.0。您应该能够在2.0.0 x86安装中安装gem。

它很容易手动安装。比起RailsInstaller，我更喜欢它，因为我需要保持其他东西的原样。方法如下：

  1. 下载并解压缩所需版本的文件。请确保下载适用于2.0.0 x86版本的DevKit的正确版本。

  2. 修复您的路径：确保您的路径包括正确的ruby、gem和DevKit目录：假设您在C:rubiesruby-2-0-0-x86中安装了ruby 2.0.0的x86版本，并在C:rubiesDevKit-xxxx-x86中安装了相关的DevKit，那么您需要在PATH:中包含这些目录

    C： \rubies\ruby-2-0-x86\binC： \rubies\ruby-2-0-x86\lib\rube\gems\2.0.0C： \rubies\DevKit-xxxx-x86\bin

  3. 将DevKit注入正确的ruby安装：一旦安装了ruby，并且在键入ruby -v时可以获得正确的信息，然后运行ruby dk.rb init——这将设置DevKit&'注入到正确的ruby版本中。（注意：我总是要编辑生成的config.yml文件，并将其放在我想要的ruby安装的正确路径中。如果你需要这样做，不要担心。）

是的。。。降级至1.9.3起作用。Tnx寻求帮助。我把总结放在这里：

  • 安装Ruby 1.9.3（不要将安装名称更改为e.RubyLang或
    配置无法自动找到）

  • 安装DevKit（遵循DevKit安装步骤）

  • 安装Nokogiri

我无法在Windows 7上安装用于Ruby 2.0的x64 Nokogiri，但二进制gem似乎可以工作。
