最近试图进入Laravel 5.1。它进展不顺利，有时它甚至不会做最基本的事情。例如：
Sebastians-MacBook-Pro:restaurante STianR$ php artisan migrate
[PDOException]
SQLSTATE[HY000] [1049] Unknown database 'dbname'
但是当我直接访问mysql时：
Sebastians-MacBook-Pro:restaurante STianR$ mysql -u root -proot

这甚至意味着什么？我试图让它与MAMP一起运行，可能是因为我有两个不同的sql服务器并且它们正在混合？
这是我的.env文件：
