为什么我的rake db:migrate会抛出错误消息？

Question

我正在开发Rails v2.3应用程序.

当我运行"rake db:migrate"时,我收到以下错误消息:

rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
rake aborted!
Access denied for user 'root'@'localhost' (using password: NO)

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

是什么原因？

看起来您的MySQL凭据未正确设置config/database.yml.
