macbookでrailsを導入したいのですが、`rails server`コマンドを実行するとエラーが吐かれます。  
以下、エラーメッセージです。

```

    $ cd ~/WebPage/JackAndBeans/Members/
    $ rails server

    Description:
        The 'rails new' command creates a new Rails application with a default
        directory structure and configuration at the path you specify.
    
        You can specify extra command-line arguments to be used every time
        'rails new' runs in the .railsrc configuration file in your home directory.
    
        Note that the arguments specified in the .railsrc file don't affect the
        defaults values shown above in this help message.
    
    Example:
        rails new ~/Code/Ruby/weblog
    
        This generates a skeletal Rails installation in ~/Code/Ruby/weblog.

[bundler 1.11.0 の変更で spring が起動しない件について -
Qiita](https://qiita.com/koshigoe/items/2304ec081a9f036e8941)

によれば、 spring のバージョンが 1.6.2 かそれ以下だと、最新の bundler の挙動に対応していない様子です。 今の spring
のバージョンはいくつでしょうか?

また、以下を実行して spring のバージョンを上げた場合、問題は解消されますか?

```

    bundle update spring
    
```
