Question

你好我的宝石文件

gem 'rails', '3.0.5'

gem 'mysql2', '< 0.3'

并在我的database.yml中编写了这段代码

development:
  adapter: mysql2
  encoding: utf8
  pool: 5
  database: railsquiz
  timeout: 5000
  username: root
  password: test
  socket: /var/run/mysqld/mysqld.sock

现在我已经运行了bundle install并获得了这个版本的mysql2-0.2.24。在做什么时

rake db:create

它给我错误
