I am developing Rails v2.3 application.
When I run "rake db:migrate" I got the following error message:
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)
What is the reason?
