gem 1.8.23、Ruby 1.9.2p318 (2012-02-14 リビジョン 34678) [x86_64-darwin10.8.0]、MongoDB 1.6.2、MongoMapper 0.11.0 および heroku を使用して Rails 3.2.3 を実行しようとしています。Rails サーバーを起動し、開発と heroku の両方で mongoDB を使用できます。しかし、何か新しいもの (ブートストラップなど) をインストールしたり、「rails s」コマンドを実行しようとすると、次のエラーが表示されます (以下に貼り付けます)。mongodb や mongo マッパーと関係があると思います。設定ファイルも同封しました。数日以来、私はこれに固執しており、ヒントやアイデアは高く評価されています. 残念ながら、これは私にとって初めての RoR アプリであり、非常にばかげているように聞こえるかもしれません。

設定ファイルにはlocalhost：28017に接続するように指示されていますが、これはWebコンソールです。おそらくlocalhost：27017が必要です。
