Laravel上的auth命名空间中没有定义命令

I'm trying to implement a remind/reset password on a Laravel application, using the official docs

On the step of running:

php artisan auth:reminders

I'm getting the error:

[InvalidArgumentException]
There are no commands defined in the "auth" namespace.

Does anyone know how to properly configure it?

Your /config/app/config.php is probably missing the Reminders service provider. Add this to your array of providers.

'providers' => array(
    ...
    'Illuminate\Auth\Reminders\ReminderServiceProvider',
    ....
)
