从 laravel 5 升级到 laravel 5.5 导致错误参数 1 传递给 App\Exceptions\Handler::report()

Question

我们正在尝试将我们的 laravel 5.0 项目升级到最新版本的 laravel（laravel 5.5 也可以）以支持 php7.1。当我们运行 composer install laravel 时会出现以下错误：

[Symfony\Component\Debug\Exception\FatalErrorException] 未捕获的 TypeError：传递给 App\Exceptions\Handler::report() 的参数 1 必须是 Exception 的实例，instanc 给出的错误 e，在 C:\xampp7\htdocs\V.E.K. 中调用。 Lexmond\vendor\laravel\framework\src\Illuminate\Foundation\Boot strap\HandleExceptions.php 在第 73 行并在 C:\xampp7\htdocs\V.E.K. 中定义。 Lexmond\app\Exceptions\Handler.php:25 堆栈跟踪： #0 C:\xampp7\htdocs\V.E.K. Lexmond\vendor\laravel\framework\src\Illuminate\Foundation\Bootstrap\HandleExceptions.ph p(73): App\Exceptions\Handler->report(Object(Error)) #1 [内部函数]：Illuminate\Foundation\Bootstrap\HandleExceptions->handleException(Object(Error)) #2 {主要} 扔了

这个错误的原因是什么？我们希望任何人都能解决我们的问题。

提前谢谢你！

<?php

/*
|--------------------------------------------------------------------------
| Create The Application
|--------------------------------------------------------------------------
|
| The first thing we will do is create a new Laravel application instance
| which serves as the "glue" for all the components of Laravel, and is
| the IoC container for the system binding all of the various parts.
|
*/

$app = new Illuminate\Foundation\Application(
    realpath(__DIR__.'/../')
);

/*
|--------------------------------------------------------------------------
| Bind Important Interfaces
|--------------------------------------------------------------------------
|
| Next, we need to bind some important interfaces into the container so
| we will be able to resolve them when needed. The kernels serve the
| incoming requests to this application from both the web and CLI.
|
*/

$app->singleton(
    'Illuminate\Contracts\Http\Kernel',
    'App\Http\Kernel'
);

$app->singleton(
    'Illuminate\Contracts\Console\Kernel',
    'App\Console\Kernel'
);

$app->singleton(
    'Illuminate\Contracts\Debug\ExceptionHandler',
    'App\Exceptions\Handler'
);

/*
|--------------------------------------------------------------------------
| Return The Application
|--------------------------------------------------------------------------
|
| This script returns the application instance. The instance is given to
| the calling script so we can separate the building of the instances
| from the actual running of the application and sending responses.
|
*/

return $app;

处理程序.php

使用异常； 使用 Illuminate\Foundation\Exceptions\Handler 作为 ExceptionHandler；

类处理程序扩展了 ExceptionHandler {

/**
 * A list of the exception types that should not be reported.
 *
 * @var array
 */
protected $dontReport = [
    'Symfony\Component\HttpKernel\Exception\HttpException'
];

/**
 * Report or log an exception.
 *
 * This is a great spot to send exceptions to Sentry, Bugsnag, etc.
 *
 * @param  \Exception  $e
 * @return void
 */
public function report(Exception $e)
{
    return parent::report($e);
}

/**
 * Render an exception into an HTTP response.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Exception  $e
 * @return \Illuminate\Http\Response
 */
public function render($request, Exception $e)
{
    return parent::render($request, $e);
}

}

你能发布你在 bootstrap/app.php 中的内容吗？

还要检查你在那个文件中是否有这个

$app->singleton(
Illuminate\Contracts\Debug\ExceptionHandler::class,
App\Exceptions\Handler::class

);
