http://ruby.railstutorial.org/のチュートリアルに従っていますが、サーバーを起動できません。私の gemfile では、ruby 2.0.0 と rails 4.0.0.rc1 を使用しています。その後、ruby 1.9.3 と rails 3.2.13 に戻そうとしましたが、まだ機能していません。

これは端末が私に言うことです：

構成ファイルに、FourTest クラスを呼び出す初期化子または行がありますか? そのクラスが見つからないためです。コードで FourTest を検索することから始めて、クラスを含むファイルの命名規則に従っていること、およびそれがデフォルトでロードされるフォルダー (models フォルダー) にあること、またはそれを使用する前に手動でロードしていること (lib.フォルダなど）。
