未定义类型 'App\Providers\Passport' laravel 8

Undefined type 'App\Providers\Passport' laravel 8

我已经按照 laravel 官方文档中的安装说明安装 passport 并且安装成功完成,但是当我尝试在 App\Providers\AuthServiceProvider 的引导方法中添加 passport 路由方法时它给我这个错误 Undefined type 'App\Providers\Passport'

这是我的composer.json

这是我的AuthServiceProvider.php

  <?php

namespace App\Providers;

use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Illuminate\Support\Facades\Gate;
use Laravel\Passport\Passport;

class AuthServiceProvider extends ServiceProvider
{
    
    protected $policies = [
        // 'App\Models\Model' => 'App\Policies\ModelPolicy',
    ];

public function boot()
{
    $this->registerPolicies();

    Passport::routes();
    

    }
}

不知道是什么问题

=>remove the comment then run.
protected $policies = [
        'App\Models\Model' => 'App\Policies\ModelPolicy',
    ];
