我知道这很简单，但我就是想不通。我需要在 Ruby 中运行一个脚本，它需要 Nokogiri。我确实有一些其他语言的经验，但在 Ruby 方面没有。

这是我的系统：

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

Ruby Development Kit (mingw64-64-4.7.2-20130224-1432) 安装在@C :\Programs\RubyDevKit

当我运行时，gem install nokogiri我收到此错误：

    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'

很容易。所以我按照上面的链接做了第 3 步。但是第 4 步说生成“config.yml”。所以我做了。现在该文件是一个带有一些注释的空列表。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 。我要说的是开发工具包安装中的步骤对我来说不够清楚。

现在更新它说 Nokogiri 的安装失败（DevKit Works 根据步骤 5：安装 json-1.8.0 1 gem 的安装文档）

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

如果您出于某种原因仍需要安装 x86 版本，或者如果您想了解如何使用 DevKit 安装和构建 gem，以下是答案：

Nokogiri 尚不支持 Ruby 2.0.0 的64 位版本。您可以阅读它并在此处关注状态。

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

手动安装非常容易。我更喜欢 RailsInstaller，因为我需要按原样维护其他东西。就是这样：

  1. 下载并解压缩所需版本的文件。请务必为 x86 版本的 2.0.0下载正确版本的 DevKit。

  2. 修复你的路径：确保你的路径包含正确的 ruby​​、gem 和 DevKit 目录：假设你安装了 x86 版本的 ruby​​ 2.0.0C:\rubies\ruby-2-0-0-x86和相关的 DevKit，C:\rubies\DevKit-xxxx-x86你需要在你的 PATH 中包含这些目录：

    C:\rubies\ruby-2-0-0-x86\bin C:\rubies\ruby-2-0-0-x86\lib\ruby\gems\2.0.0 C:\rubies\DevKit-xxxx-x86 \垃圾桶

  3. 将 DevKit 注入正确的 ruby​​ 安装：一旦您安装了 ruby​​ 并且可以在键入时获得正确的信息ruby -v，然后运行ruby dk.rb init​​- 这将设置 DevKit 并“注入”到正确的 ruby​​ 版本中。（注意，我总是必须编辑生成的config.yml文件并将其放入我想要的 ruby​​ 安装的正确路径。如果你需要这样做，请不要出汗。）

是的...降级到 1.9.3 有效。寻求帮助。我把摘要放在这里：

  • 安装 Ruby 1.9.3（不要将安装名称更改为 ex.RubyLang 或
    配置不会自动找到它）

  • 安装 DevKit（按照 DevKit 安装步骤）

  • 安装 Nokogiri

我无法在 Windows 7 上为 Ruby 2.0 安装 x64 Nokogiri，但二进制 gem似乎可以正常工作。
