Laravel 6：尚未设置外观根

Question

我已将我的网站从 Laravel 5.8 迁移到 Laravel 6，在Composer 更新后，我在网站上出现此错误，并且仅使用命令php artisan：

PHP Fatal error:  Uncaught RuntimeException: A facade root has not been set. in /var/www/html/vendor/laravel/framework/src/Illuminate/Support/Facades/Facade.php:242
Stack trace:
#0 /var/www/html/app/Exceptions/Handler.php(48): Illuminate\Support\Facades\Facade::__callStatic('check', Array)

我已经采取了一个新的 laravel 6 文件config\app.php和一个新的.env 但总是这个错误......

我该如何解决？

Answer 1

最后我找到了一个解决方案，我复制了一个 laravel 6 配置文件：config/session.php并且它有效。
