Answer 1

您需要为新防护定义提供程序，否则它将引发错误。您的提供商也应该拼写为"admins">，因为您正在为管理员引用特定的迁移表

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => AppUser::class,
    ],

    'admins' => [
        'driver' => 'eloquent',
        'model' => AppAdmin::class,
    ],
],

一切都很好，我只是在控制器中被称为旧的默认用户身份验证，我在旧项目中进行了修改，现在我安装了新项目，然后移动除用户.php默认模型以外的所有文件

 $companyAuth = auth()->guard('user'); //called wrong default 
 $companyAuth = auth()->guard('employee'); //now working fine
