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laravel的最新版本（laravel 5.5也可以），以支持php7.1。当我们运行composer安装时，laravel给出了以下错误：

[Symfony\Component\Debug\Exception\FatalErrorException]未捕获类型错误：传递给App\Exceptions\Handler：：report（）的参数1必须是异常实例，给定错误实例，在C:\xampp7\htdocs\V.e.K.Lexmond\vendor\laravel\framework\src\Illuminate\Foundation\Boot strap\HandleExceptions中调用。php位于第73行，在C:\xampp7\htdocs\V.E.K.Lexmond\app\Exceptions\Handler中定义。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）：应用程序\异常\处理程序-

这个错误的原因是什么？我们希望任何人都能为我们的问题找到解决方案。

提前谢谢！

<?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;

Answer 2

Handler.php

使用异常；使用Illumate\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);
}

}

你能在bootstrap/app中发布你拥有的吗。php？

还要检查一下文件中是否有这个

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

）；
