Ich versuche, mit MongoDB (mongoid) und MySQL zusammen eine Anwendung in Rails 4 zu erstellen. Aber ich kann es nicht einrichten.

Ich folge den Schritten unten:

rails new myapp -d mysqlThen fügte diese Zeilen zu Gemfile hinzu:
gem "mongoid"
gem "bson_ext"bundle installrails g mongoid:config

Schritt 4 schlägt fehl. Ich kann das Problem nicht herausfinden. Es wird der folgende Fehler angezeigt.
