SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) - laravel

I am using MAMP in the macOs. I was download the laravel 5 from cpanel. I am getting this error:

SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) (SQL: select * from `products` where `pro_status` = 1 and `pro_stock` > 0 order by `pro_id` desc limit 8)

But can't fix it.
