运行第一条语句后，您需要对文件进行一些更改vendor/spatie/laravel-permission/src/PermissionServiceProvider.phpcomposer require spatie/laravel-permission这是第 61/62 行的实际代码：$this->app->bind(PermissionContract::class, $config['permission']);$this->app->bind(PermissionContract::class, $config['role']);需要更改以下内容：$this->app->bind(PermissionContract::class, isset($config['permission']));$this->app->bind(PermissionContract::class, isset($config['role']));之后，更改再次运行，仅此而已。在最新版本的 PHP 上，您必须使用 isset（） 检查变量是否为空：composer require spatie/laravel-permission
