當我嘗試使用修補程序插入管理員數據時，我遇到了 php 錯誤問題。我正在創建一個多重身份驗證用戶，其中一個用于用戶，一個用于管理員。PHP 錯誤：在第 13 行的 c:/S/htdocs/iV/app/Models/Admin.php 中找不到類“Illuminate/Foundation/Auth/Admin”我該如何解決該錯誤？Admin<?phpnamespace App\Models;use Illuminate\Database\Eloquent\Factories\HasFactory;use Illuminate\Database\Eloquent\Model;use Illuminate\Contracts\Auth\MustVerifyEmail;use Illuminate\Foundation\Auth\Admin as Authenticatable;use Illuminate\Notifications\Notifiable;use App\Notifications\AdminResetPasswordNotification;class Admin extends Authenticatable{    use HasFactory, Notifiable;    protected $guard = 'admin';    /**     * The attributes that are mass assignable.     *     * @var array     */    protected $fillable = [        'name', 'email', 'password',    ];    /**     * The attributes that should be hidden for arrays.     *     * @var array     */    protected $hidden = [        'password', 'remember_token',    ];    /**     * The attributes that should be cast to native types.     *     * @var array     */    protected $casts = [        'email_verified_at' => 'datetime',    ];} 我嘗試刪除composer.lock文件，然后再次安裝它，我也這樣做了。composer dump-autoload composer install --no-scripts composer update
