Laravel本地化错误："setlocale()：参数#1($category)的类型必须是int，给定的是Illuminate\Http\Request"

我用Laravel 10开发了多语言网站.一切都运行得很好，因为Composer不支持我的服务器上的laravel 10库，所以我创建了一个laravel 9项目并只移动了以下文件夹；

/app
/public
/resources
/routes
/composer.json

然后我做了Composer安装和php artisan优化，结果是成功的.但问题是，当我访问我的网站时，我收到以下错误:

setlocale(): Argument #1 ($category) must be of type int, Illuminate\Http\Request given

/app/Http/Kernel.php :个
