初めてのRailsアプリケーションの実行中にエラーが発生しました

Question

「Rubyの学習」という本があります。レールのセクションの下には、簡単なRails Webアプリケーションの作成手順が段階的に示されています。

それは終わり近くに、コマンドを入力言う：

./script/generate scaffold addressbook addressbook

しかし、途中、私はエラーを取得して：

wrong number of arguments (1 for 2)

私はこれが原因でわずかなバージョンの違いであると仮定し、私はカント私のレールアプリケーションを動作させて、ここの誰かが私を助けてくれることを期待していましたか？

Description: 
    Scaffolds an entire resource, from model and migration to controller and 
    views, along with a full test suite. The resource is ready to use as a 
    starting point for your RESTful, resource-oriented application. 

    Pass the name of the model (in singular form), either CamelCased or 
    under_scored, as the first argument, and an optional list of attribute 
    pairs. 

    Attribute pairs are column_name:sql_type arguments specifying the 
    model's attributes. Timestamps are added by default, so you don't have to 
    specify them by hand as 'created_at:datetime updated_at:datetime'. 

    You don't have to think up every attribute up front, but it helps to 
    sketch out a few so you can start working with the resource immediately. 

    For example, 'scaffold post title:string body:text published:boolean' 
    gives you a model with those three attributes, a controller that handles 
    the create/show/update/destroy, forms to create and edit your posts, and 
    an index that lists them all, as well as a map.resources :posts 
    declaration in config/routes.rb. 

    If you want to remove all the generated files, run 
    'script/destroy scaffold ModelName'. 

Examples: 
    `./script/generate scaffold post` 
    `./script/generate scaffold post title:string body:text published:boolean` 
    `./script/generate scaffold purchase order_id:integer amount:decimal`
