【问题讨论】：

你读过那个问题https://***.com/questions/59084991/laravel-6-a-facade-root-has-not-been-set

这能回答你的问题吗？ Laravel 6 : A facade root has not been set

【参考方案1】：

在你的 composer.json 文件中你应该有这个：

"laravel/framework": "^6.0",
"php": "^7.2",
"phpunit/phpunit": "^8.0"

然后在控制台中执行composer update，所以如果你使用的是助手字符串和数组 在这种情况下，您需要使用以下命令安装包 laravel/helpers：

composer require laravel/helpers

然后通过调用类的方法来更改助手 Illuminate\Support\Str 和 Illuminate\Support\Arr，如果您有其他问题，请在此处分享您的 composer.json 以查看更多详细信息。
