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.

    Move to the directory created by

    rails new sample, and then runrails sagain. Here is an example where the application name ishoge:

    rails new hoge
    cd hoge
    rails s

    If you still cannot runrails s, try the following:

    bundle install --path =./vendor/bundle

    bin/rails s
