Laravel 7 从 laravel 6 升级时抛出错误 255

Question

我刚刚尝试将 Laravel 从 v6 升级到 v7，我的 php 版本是 7.3，我按照 laravel 站点上的说明升级了所有依赖项，并删除了冲突的包，升级似乎已完成，但出现以下错误：

Generating optimized autoload files> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi
PHP Fatal error:  Declaration of App\Exceptions\Handler::report(Exception $exception) must be compatible with Illuminate\Foundation\Exceptions\Handler::report(Throwable $e) in /var/www/html/virtuozzo-api/app/Exceptions/Handler.php on line 8
PHP Fatal error:  Uncaught ReflectionException: Class App\Exceptions\Handler does not exist in /var/www/html/virtuozzo-api/vendor/laravel/framework/src/Illuminate/Container/Container.php:803

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 255

我已经尝试删除 vendor 文件夹并重新安装，也尝试使用 composer dump autoload，并尝试清除 laravel 缓存，但总是出现相同的错误。

Answer 1

在您的 app/Exceptions/Handler.php 文件中：将 Exception 类型提示替换为 Throwable 类型提示。

如Upgrade guide所述。

Answer 2

这是不同之处

这是更新后的文件，

<?php

namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
use Throwable;

class Handler extends ExceptionHandler
{
    /**
     * A list of the exception types that are not reported.
     *
     * @var array
     */
    protected $dontReport = [
        //
    ];

    /**
     * A list of the inputs that are never flashed for validation exceptions.
     *
     * @var array
     */
    protected $dontFlash = [
        'password',
        'password_confirmation',
    ];

    /**
     * Report or log an exception.
     *
     * @param Throwable $exception
     * @return void
     *
     * @throws Exception
     */
    public function report(Throwable $exception)
    {
        parent::report($exception);
    }

    /**
     * Render an exception into an HTTP response.
     *
     * @param Request $request
     * @param Throwable $exception
     * @return Response
     *
     * @throws Throwable
     */
    public function render($request, Throwable $exception)
    {
        return parent::render($request, $exception);
    }
}
