Laravel say that Auth guard [] is not defined

Question

at routes.php

Answer 1

In case you edited your config/auth.php, e.g. to add another guard and your config is cached, your guards may not be reloaded. If you experience this problem, clearing the config will fix it.

$php artisan config:clear or $php artisan config:cache

I'm using laravel 5.5
