Php 没有名为“Admin”的角色`

我尝试使用Spatial包和laracasts/flash包创建角色和权限。我遵循这个教程 但当我想迁移并授予权限时，我遇到了以下错误：

？[41；1m空间\权限\例外\角色不存在？[49；22m

？[39；1m没有名为

我已经尝试为我的用户模型提供受保护的

$guard\u name='api'；

并尝试将auth.php文件

'defaults' => [
        'guard' => 'api',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
    ],

这是我的用户模型

{
    use HasFactory, Notifiable, HasRoles;

    protected $guard_name ='api';

        'password',

    protected $hidden = [

        'remember_token',
    ];

    /**
