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. 

Ich bin auf Ubuntu 16.04, Datenbank mysql. Was für ein Problem kann es sein? habe ich diese Führungsschienen mit dem Befehl https://gorails.com/setup/ubuntu/16.04

Answer 1

1. erstellen Schienen-Projekt zu installieren: rails new my_app_name.

2. Wechseln Sie das Verzeichnis in den Ordner: cd my_app_name.

3. Run, was andere Befehle, die Sie mögen, z.B. rails server.
