You dont have any atachRole method in your User model. So it seem's you have missed step #4 of installation section.

Add the Laratrust\Contracts\LaratrustUser interface and Laratrust\Traits\HasRolesAndPermissions trait in your user classes ( normally located in App\Models\User ).

use Laratrust\Contracts\LaratrustUser;
use Laratrust\Traits\HasRolesAndPermissions;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements LaratrustUser // 
{
    use HasRolesAndPermissions;  // <- This will add some methods and property to your class ( attachRole included )

    // ...
}
