我正在尝试运行rake命令来为我的项目构建数据库。但我正在惹恼以下错误。
Harshas-MacBook-Pro:noise harshamv$ rake db:create
Couldn't create database for {"adapter"=>"mysql2", "encoding"=>"utf8", "database"=>"noise_development", "pool"=>5, "username"=>"hmv", "password"=>2206, "socket"=>"/var/run/mysqld/mysqld.sock"}, {:charset=>"utf8", :collation=>"utf8_unicode_ci"}
(If you set the charset manually, make sure you have a matching collation)
