Answer 1

只需按照文档，您必须已安装php7.2.5

在 composer.json 文件中将 laravel/framework 依赖项更新为 ^7.0。

此外，将您的 nunomaduro/collision 依赖项更新为 ^4.1，

phpunit/phpunit 对 ^8.5 的依赖，

门面/点火到>`^2.0

之后作为下一步。

应用程序App\Exceptions\Handler类的 report 和 render 方法应该接受Throwable接口的实例而不是 Exception 实例：

use Throwable; // add this line

public function report(Throwable $exception); // replace Exception with Throwable
public function render($request, Throwable $exception); // replace Exception with Throwable

在那次跑步之后

composer update

Answer 2

根据 Laravel 文档 从 升级laravel 6到laravel 7

laravel/framework将您的依赖项更新到^7.0您的composer.json 文件中。此外，将您的nunomaduro/collision依赖项更新为 ^4.1、phpunit/phpunit依赖项^8.5和facade/ignition`^2.0。

然后在终端中运行composer update

composer update
