Ruby on Rails教程，第3章Gemfile錯誤

Question

我正在學習本教程：http://ruby.railstutorial.org/chapters/static-pages#top ...您可以[ctrl + f]至Listing 3.1. A Gemfile for the sample app來查找我的位置。

我只是複製並粘貼gemfile，因爲它是在那裏給出的（它沒有工作，所以我繼續嘗試從10.42開始，因爲它是立即連接到[ctrl + f]點之上的，因爲我會必須在某些時候使用它。）

對於10.42列表，它給了我一個錯誤，Could not find gem 'will_paginate (= 3.0.pre2) ruby' in the gems available on this machine。

• Rails是3.0.11版本
• 紅寶石版本：1.8.7（2012-02-08 PATCHLEVEL 358）[I386-的cygwin]

下面是一個複製粘貼從顯示錯誤的終端。該格式是可怕的在這裏，所以我也把它設在這裏一個谷歌文檔頁面上：https://docs.google.com/document/d/1SJsfIOtKKR2Rb228kgfpTdpYhGsWLCwfkORXJA1qYBs/edit

寶石原生擴展（C代碼）在Windows上安裝時，他們往往需要ruby devkit除了MinGW的。

RubyInstaller開發工具包（DevKit）是基於MSYS/MinGW的工具包，它使您能夠構建許多可用於Ruby的本機C/C++擴展。
