    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,
        or in $XDG_CONFIG_HOME/rails/railsrc if XDG_CONFIG_HOME is set.
    
        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.
    
```

このように返されました。  
そして、http://localhost:3000/  
にアクセスしたところ、このサイトにアクセスできませんとエラーが出ました。  
どうすれば。正常にページを表示できるでしょうか。

question
ruby-on-rails ruby
rails serverができない
rails newコマンドで作成したアプリにcdコマンドで移動する必要があります。  
rails newをした時にはまだrailsアプリの中には入っていないので、cdする必要があります
