命名空间声明语句错误

Question

我尝试使用它来创建我的网站表单，但它可以显示名称空间声明错误。

错误：命名空间声明语句必须是第一个语句或脚本中的任何声明调用之后

        Open config/app.php and update as follows:

        'providers' => [
           ...
           Illuminate\Html\HtmlServiceProvider::class,
        ],

        'aliases' => [
             ...

            'Form'=> Illuminate\Html\FormFacade::class, 
            'Html'=> Illuminate\Html\HtmlFacade::class,
        ],
