Answer 1

Try this. Import HasRoles package as follow;

use Spatie\Permission\Traits\HasRoles;

Answer 2

I'm guessing you're using the Spatie Laravel Permission package.

If so, you need to import the class like so:

use Spatie\Permission\Traits\HasRoles;

Answer 3

Run this command

composer install
