Question

以下是我所做的一步一步。

cd ~/rails_projects 
rails new demo_app1
cd demo_app1

（修改了我的gem文件for rails 3.2.13.Ssqlite3到1.3.5 sass-rails到3.2.4 coffee rails到3.2.2 uglier到1.2.3 jquery-rails到2.0.1和pg到0.12.2 ）

然后捆绑更新

bundle install --without production

git init
git add .
git commit -m "initial commit"

然后rails生成脚手架用户名：string email：string

但它没有生成脚手架我得到的是下面发布的选项菜单。

Chris-Schusters-MacBook-Pro:demo_app1 schust49$ 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/schust49/.rvm/rubies/ruby-1.9.3-p484/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]           # Don't create a Gemfile
      [--skip-bundle]            # Don't run bundle install
  -G, [--skip-git]               # Skip Git ignores and keeps
  -O, [--skip-active-record]     # Skip Active Record files
  -S, [--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]        # Skip JavaScript files
      [--dev]                    # Setup the application with Gemfile pointing to your Rails checkout
      [--edge]                   # Setup the application with Gemfile pointing to Rails repository
  -T, [--skip-test-unit]         # Skip Test::Unit files
      [--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]  # Run but do not make any changes
  -q, [--quiet]    # Suppress status output
  -s, [--skip]     # Skip files that already exist

Rails options:
  -h, [--help]     # Show this help message and quit
  -v, [--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.

我哪里出错了，我该如何解决这个问题呢？

Answer 1

首先你必须在gemfile

中安装`gem'sqlite3'

然后捆绑安装......

首先，如果您的计算机上安装了RVM，然后选择带有rvm的ruby版本，那么

检查ruby版本

ruby -v

和rails version

rails -v

如果两者都为您提供了在您的应用程序中使用的版本并且捆绑完成，那么它将不会提供上述选项并创建模型
