无法在Windows中安装Nokogiri for Ruby

Question

我知道这很简单,但我无法理解.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,但不是Ruby.

这是我的系统:

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

Ruby开发工具包(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.我仍然无法安装Nokogiri,因为上面的错误,我似乎没有得到任何DevKit.我的意思是开发套件安装中的步骤对我来说不够清楚.

---

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

Answer 1

更新:自1.6.2版本中,引入nokogiri现在不支持的Ruby 2.0.0的64位版本.(注意,它需要libxml> = 2.6.21)

如果由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,那么这就是答案:

Nokogiri尚不支持64位版本的Ruby 2.0.0.您可以阅读它并按照此处的状态进行操作.

但Nokogiri 确实支持x86版本的ruby 2.0.0.您应该能够在2.0.0 x86安装上安装gem.

手动安装非常简单.我更喜欢RailsInstaller,因为我需要维护其他东西.这是如何做:

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. 修复您的路径:确保您的路径包含右侧ruby,gem和DevKit目录的目录:假设您已将x86版本的ruby 2.0.0安装到C:\rubies\ruby-2-0-0-x86相关的DevKit中,C:\rubies\DevKit-xxxx-x86您需要在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\BIN

3. 将DevKit注入正确的ruby安装:一旦安装了ruby并在键入时可以获得正确的信息ruby -v,然后运行ruby dk.rb init- 这将使DevKit设置并'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,并将其放入我想要的ruby安装的正确路径中.如果需要,请不要冒汗.)
