Question

我目前正在做Michael Hartls Railstutorials并遇到了一个我不太了解的问题。当我尝试使用此命令生成用户脚手架时

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

我只是列出了rails命令的选项，例如这个

   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$

但是没有生成任何视图或控制器。关于我在这里错过了什么的任何提示？非常感谢

我想您已经使用一个版本的Rails创建了rails new，而不是在Gemfile中更改了它。因此，如果您运行任何rails generate命令，它将使用新版本，但它不会将您的目录检测为任何项目，因此它不会创建任何内容。

Rails脚手架没有按预期工作
