私はmacportsに移動し、rake db：migrateを実行しようとしましたが、
$ rake db:migrate(in /Users/me/work/myproject)
rake aborted!
Mysql::Error: Table 'myproject_development.users' doesn't exist: SHOW FIELDS FROM `users`
私のdatabase.ymlかもしれないと思いますか？現在macportsとmysql5を使用しているので、何を変更する必要がありますか。これ以前は、CocoaMySqlを使用してdbmyproject_developmentを作成するだけでした。
