Ruby on Railsチュートリアル、第3章Gemfileエラー

Question

私はこのチュートリアルで作業しています：http://ruby.railstutorial.org/chapters/static-pages#top ... Listing 3.1. A Gemfile for the sample appに[Ctrl + F]を押して、私がどこにいるかを見つけることができます。

gemfileがコピーされて貼り付けられているだけです（動作しませんでしたので、[Ctrl + F]の直上にリンクされているように10.42から試しました。とにかくそれを使用しなければなりません。）

10.42のリストの場合、それは私にエラーCould not find gem 'will_paginate (= 3.0.pre2) ruby' in the gems available on this machineを与えています。

• Railsがバージョン3.0.11
• Rubyのバージョンである：どのような次はからのコピー＆ペーストである1.8.7（2012-02-08パッチレベル358）[I386-cygwinの]

エラーを示す端末。書式設定は、ここでひどいですので、私もここにあるGoogleドキュメントのページにそれを入れている：Windows上でそれらをインストールするときにネイティブ拡張（Cコード）とhttps://docs.google.com/document/d/1SJsfIOtKKR2Rb228kgfpTdpYhGsWLCwfkORXJA1qYBs/edit

宝石は、多くの場合、mingwのほかruby devkitが必要です。

RubyInstaller開発キット（DevKit）は、Rubyで利用可能なネイティブC/C++拡張の多くをビルドできるようにするMSYS/MinGWベースのツールキットです。
