执行迁移脚本时 Engine Yard 部署失败

Question

我正在尝试使用 engineyard gem 在基于 Rails 2 的应用程序上部署 ruby​​，并收到以下错误：

ey deploy --migrate=rake db:migrate
Beginning deploy for 'test' in 'test' on server...

Run "rake db:migrate" to update your database then try again.

* any deploy hooks ran, be careful if they were destructive
* any migrations ran, be careful if they were destructive
* your old code is still symlinked as current

以前有人遇到过同样的问题吗？
