Question

I use ruby1.8.7, rails3.0.7 and mysql2(0.2.11). When I ran rake db:create for the new application, I got the following message. Is there somebody solve this problem before? Could you help me?

rake db:create --trace

You probably have an integer set as your username or password in database.yml – try wrapping it in quotes
