無法在Windows中安裝Ruby的Nokogiri

Question

我知道這很簡單，但我無法弄清楚。我需要在Ruby中運行腳本，它需要Nokogiri。我在其他語言方面有一些經驗，但在Ruby中沒有。

這裏是我的系統：

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

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

當我運行gem install nokogiri我得到這個錯誤：

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' 

很容易的。所以我遵循the link of above並做了第3步。但第4步說生成「config.yml」。所以我做了。現在該文件是一個帶有一些註釋的空白列表。由於上面的錯誤，我仍然無法安裝Nokogiri，而且我似乎無法使用DevKit。我所說的是，開發套件安裝中的步驟對我來說還不夠清楚。

---

更新現在說安裝引入nokogiri的失敗（根據步驟5的devkit工程：安裝JSON-1.8.0 1寶石安裝文件）

Answer 1

更新：自1.6.2版本中，引入nokogiri現在確實支持64位版本的Ruby 2.0.0。 （請注意，它需要的libxml> = 2.6.21）

這裏的答案，如果你還需要安裝x86版本出於某種原因，或者如果你想了解如何安裝和使用的devkit建立一個寶石：

Nokogiri還不支持64位版本的Ruby 2.0.0。你可以閱讀關於它和follow the status here。

但是Nokogiri 確實支持x86版本的ruby 2.0.0。您應該能夠在2.0.0 x86安裝上安裝gem。

手動安裝非常簡單。我更喜歡RailsInstaller，因爲我需要保持其他東西。操作方法如下：

1. 下載並解壓縮所需版本的文件。確保download the correct version of DevKit適用於2.0.0的x86版本。

2. 解決您的路徑：請確保您的路徑包括目錄，以正確的紅寶石，寶石，並顯示目錄的devkit： 假設你安裝了Ruby 2.0.0的x86版本到C:\rubies\ruby-2-0-0-x86和相關的devkit到C:\rubies\DevKit-xxxx-x86您需要將這些目錄包含在PATH中：

   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. 將DevKit注入右邊的ruby install：一旦你安裝了ruby並且可以獲得輸入ruby -v後輸入正確的信息，然後運行ruby dk.rb init - 這將使DevKit將&'注入'設置爲正確的ruby版本。 （注：我總是以編輯製作並放在正確的路徑紅寶石安裝我想config.yml文件。別擔心，如果你需要做的。）

Answer 2

是...降級到1.9.3工作。 Tnx求助。我把這裏的總結：

• 安裝Ruby 1.9.3（不要更改安裝名稱ex.RubyLang或
  配置不能自動找到它）

• 安裝的devkit（按照安裝的devkit步驟）

• 安裝引入nokogiri

Answer 3

我是不是能夠在Windows 7上爲Ruby 2.0安裝x64 Nokogiri，但binary gem似乎正在工作。
