ArgumentError、作成アクションの引数数が2です（0の場合は2）、Herokuでは動作しますがローカルサーバでは動作しません

Question

最近私は第三者によって私のために開発されたRoRアプリケーションを手に入れました。私が望む機能Heroku上で動作しますが、localhost：3000で実行しようとすると、ArgumentErrorが発生します。私はコードを変更していない、私はちょうどgithubからそれを取り出し、新しい変更を実装するためにローカル開発サーバー上でそれを実行しようとしました。

我々はルビー1.9.2を実行しているが、

私が保存しようとするたびに3.0.7レール...私はこの問題について、それらを求めてきましたが、彼らは、原因がわからないので、ここで行きます私のサイトのプロジェクト、または.saveがオブジェクトに対して呼び出されるたびに、ArgumentError、引数の数が間違っています（0は2）。

projects_controllerからのコード、ライン24は声明

def create 
    @project = Project.new(params[:project]) 
    @project.memberships.build(:user_id => current_profile.id, :pending => false) 

    if @project.save 
     redirect_to destination, :notice => 'Project was successfully created.' 
    else 
     build_project_associations_for_nested_forms 
     render :action => 'new' 
    end 
    end 

が、私はこれで少しは新たなんだ場合には、そうです問題を特定するために他に何が必要なのかよく分かりません。

Answer 1

WEBrick以外のものを使ってみましたか？ Thin（gem install thin）をインストールして、問題が解消されないかどうか確認してください。

Answer 2

あなたが必要なすべての宝石を持っている、実行バンドルがインストールされていることを確認します：

bundle install 

再起動アプリ、うまくいけば、それが役立ちます。
