私の質問は、なぜこのエラーが表示される必要があるのか​​ということです。

main：Objectの未定義のメソッド `root'

自分のサイトにアクセスしてPhusionのエラーページを見ると、これが表示されます。長い出力は次のとおりです。

おそらくアプリは config/routes.rb でルートルートを定義することを望んでいます (詳細については config/routes.rb を開いてください)

これがここで役立つことを願っています...私は基本的に新規インストールをしました。私は足場の呼び出しを行いました:

mirv@rorblog:~/workspace/workspace (master) $ rails g scaffold User userID:integer index  name:string email:string password:string lastLogin:datetime

どちらが明らかに間違っていました...しかし、それを元に戻す方法は? 「rake db:migrate」を誤って実行してしまったので、単純なコマンドで削除できると考えました。間違っていますが、幸いなことに、github を比較したところ、routes.rb ファイルの先頭に違いがあることに気付きました。 

resources :users

ruby の scaffold destroy コマンドは、routes.rb ファイルに小さな行を 1 行残していたため、全体が台無しになりました。github で diff を比較しなければ、私は気づかなかったでしょう。以下は、私のように盲目的にグーグルで検索した場合の元のエラーです...
