本文介绍了无法在 Windows 中为 Ruby 安装 Nokogiri的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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.我确实在其他语言方面有一些经验，但在 Ruby 方面没有.

I know this is simple but I just can't figure it out. I need to run a script in Ruby and it requires Nokogiri. I do have some experience in other languages but not in Ruby.

这是我的系统:

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

Ruby 2.0.0-p195 (x64) is installed @ C:\Programs\RubyLanguage

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

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

当我运行 gem install nokogiri 时出现此错误:

When I run gem install nokogiri I get this error:

    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.所以我跟着上面的链接并做了第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.由于上述错误，我仍然无法安装 Nokogiri 并且我似乎无法使用 DevKit .我要说的是，Development Kit 安装中的步骤对我来说还不够清楚.

Easy enough. So I followed the link of above and did to step 3. However step 4 says generate "config.yml". So I did. Now the file is an empty list with some comments. I still can't install Nokogiri because of error above and I don't seem to get anywhere with DevKit . What I am saying is that the steps in the Development Kit installation is not clear enough for me.

更新现在说 Nokogiri 安装失败(DevKit Works 根据第 5 步:为 json-1.8.0 安装文档安装了 1 个 gem )

Update it now says installation of Nokogiri failed ( DevKit Works according to step 5 : Installing documentation for json-1.8.0 1 gem installed )

推荐答案

更新:从 1.6.2 版开始，Nokogiri 现在确实支持 64 位版本的 Ruby 2.0.0.(注意它需要 libxml >= 2.6.21 )

Update: As of version 1.6.2, Nokogiri now does support the 64-bit version of Ruby 2.0.0. (Note that it requires libxml >= 2.6.21 )

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

Here's the answer if you still need to install the x86 version for some reason or if you want to understand how to install and build a gem using DevKit:

Nokogiri 尚不支持64 位 Ruby 2.0.0 版本.您可以阅读它和关注这里的状态.

Nokogiri does not yet support the 64-bit version of Ruby 2.0.0. You can read about it and follow the status here.

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.

But Nokogiri does support the x86 version of ruby 2.0.0. You should be able to install the gem in on 2.0.0 x86 install.

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.方法如下:

It's pretty easy to hand-install. I prefer that over RailsInstaller because I need to maintain other things as they are. Here's how:

  1. 下载并解压缩所需版本的文件.请务必下载适用于 x86 版本 2.0.0 的正确版本的 DevKit.

修复您的路径:确保您的路径包含正确的 ruby​​、gem 和 DevKit 目录:假设您将 x86 版本的 ruby​​ 2.0.0 安装到 C:\rubies\ruby-2-0-0-x86 并将关联的 DevKit 安装到 C:\rubies\DevKit-xxxx-x86 你需要在你的 PATH 中包含这些目录:

Fix your path: Make sure your path includes the directories to the right ruby, gem, and DevKit dirs: Assume you installed the x86 version of ruby 2.0.0 into C:\rubies\ruby-2-0-0-x86 and the associated DevKit into C:\rubies\DevKit-xxxx-x86 you will need to include these directories in your PATH:

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

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

将 DevKit 注入正确的 ruby​​ 安装:一旦你安装了 ruby​​ 并且当你输入 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​​ 安装的正确路径中.如果您需要这样做，请不要担心.)>

Inject DevKit into the right ruby install: Once you have ruby installed and can get the correct info when you type ruby -v, then run ruby dk.rb init -- which will get DevKit set up & 'injected' into the correct ruby version. (N.B. I always have to edit the config.yml file that is produced and put in the correct path to the ruby installation I want. Don't sweat it if you need to do that.)
