Rails腳手架按預期工作

Question

我目前正在做Michael Hartls Railstutorials，並遇到了一個我不太明白的問題。 當我嘗試生成用戶腳手架使用此命令

benjamins-air-3:demo_app caspar$ rails generate scaffold User name:string email:string 

我只是讓正在生成任何意見或控制器一對軌道命令的選項，比如這

benjamins-air-3:demo_app caspar$ rails generate scaffold User name:string email:string 
Usage: 
    rails new APP_PATH [options] 

Options: 
    -r, [--ruby=PATH]          # Path to the Ruby binary of your choice 
                 # Default: /Users/caspar/.rvm/rubies/ruby-2.0.0-p451/bin/ruby 
    -b, [--builder=BUILDER]        # Path to a application builder (can be a filesystem path or URL) 
    -m, [--template=TEMPLATE]        # Path to an application template (can be a filesystem path or URL) 
     [--skip-gemfile], [--no-skip-gemfile]    # Don't create a Gemfile 
     [--skip-bundle], [--no-skip-bundle]    # Don't run bundle install 
    -G, [--skip-git], [--no-skip-git]      # Skip Git ignores and keeps 
    -O, [--skip-active-record], [--no-skip-active-record] # Skip Active Record files 
    -S, [--skip-sprockets], [--no-skip-sprockets]   # Skip Sprockets files 
    -d, [--database=DATABASE]        # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc) 
                 # Default: sqlite3 
    -j, [--javascript=JAVASCRIPT]       # Preconfigure for selected JavaScript library 
                 # Default: jquery 
    -J, [--skip-javascript], [--no-skip-javascript]  # Skip JavaScript files 
     [--dev], [--no-dev]        # Setup the application with Gemfile pointing to your Rails checkout 
     [--edge], [--no-edge]        # Setup the application with Gemfile pointing to Rails repository 
    -T, [--skip-test-unit], [--no-skip-test-unit]   # Skip Test::Unit files 
     [--old-style-hash], [--no-old-style-hash]   # Force using old style hash (:foo => 'bar') on Ruby >= 1.9 

Runtime options: 
    -f, [--force]     # Overwrite files that already exist 
    -p, [--pretend], [--no-pretend] # Run but do not make any changes 
    -q, [--quiet], [--no-quiet]  # Suppress status output 
    -s, [--skip], [--no-skip]  # Skip files that already exist 

Rails options: 
    -h, [--help], [--no-help]  # Show this help message and quit 
    -v, [--version], [--no-version] # Show Rails version number and quit 

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. 
    See the README in the newly created application to get going. 
benjamins-air-3:demo_app caspar$ ruby -v 
ruby 2.0.0p451 (2014-02-24 revision 45167) [x86_64-darwin13.1.0] 
benjamins-air-3:demo_app caspar$ rails -v 
Rails 3.2.14 
benjamins-air-3:demo_app caspar$ 

上市，但。任何提示，我在這裏錯過了什麼？非常感謝

我想你已經創建了rails new使用一個版本的Rails，並改變它在Gemfile。因此，如果您運行任何rails generate命令，它將使用新版本，但它不會將您的目錄檢測爲任何項目，因此它不會創建任何內容。
