Trait ‘Illuminate\Auth\UserTrait’ not found

laravel小白，laravel5.7

<?php

namespace App;

use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
use Illuminate\Database\Eloquent\Model;
class Badmin extends Model implements UserInterface, RemindableInterface {

    use UserTrait, RemindableTrait;

    protected $table = 'badmin';

    protected $hidden = array('password');

    public static $rules = [
        'nickname' => 'required|alpha_num|min:2',
        'username' => 'required',
        'email'=>'required|email|unique:badmin',
        'password'=>'required|alpha_num|between:6,12|confirmed',
    ];
}

一直提示找不见这个类，用了 php artisan make:auth
还是不起作用
