这是我的database.yml文件

development:
  adapter: MysqL
  encoding: utf8
  reconnect: false
  database: shareBox_development
  pool: 5
  username: root
  password:
  host: localhost

香港专业教育学院重新安装Ruby,Rails和MysqL的,但仍然得到相同的错误,任何帮助将不胜感激.干杯

解决方法:

您应该在GemFile中调整rake的版本.

Rake 0.9刚出来但打破了Rails.

这是dhh的推文：

昨天发布的Rake 0.9打破了Rails(及其他).当我们等待修复时,您会在Gemfile中需要gem’rake’,’0.8.7′.

试试吧

编辑：另外,如果您确实需要Rake 0.9而不是Rake 0.8.7,请参见that post.也许这种修复对您有用.
