我对Laravel相对较新，我正在尝试学习空间/laravel-permission。我用的是Laravel 10。我正在尝试用角色和用户来播种我的数据库。
我得到这个错误：
Spatie\Permission\Exceptions\RoleDoesNotExist没有名为admin的角色。
这是我的代码。正如您在RoleSeeder中看到的，我确实创建了一个管理员角色。我在User模型中也有HasRoles trait。我不知道我做错了什么。任何帮助将不胜感激。

• • RoleSeeder. php**

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use Spatie\Permission\Models\Role;

class RoleSeeder extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run(): void
    {
        Role::create(['name' => 'super admin', 'team_id' => 1, 'guard_name' => 'web']);
        Role::create(['name' => 'admin', 'team_id' => 1, 'guard_name' => 'web']);
        Role::create(['name' => 'user', 'team_id' => 1, 'guard_name' => 'web']);
    }
}

    {
        $user = User::create( [
            'name' => 'admin',
            'email' => 'admin@gmail.com',
            'email_verified_at' => now(),
