Composer更新打破了网站Laravel 5.2

我不小心运行了composer update，它破坏了我的网站。我使用的是Laravel5.2。现在，我得到了这个错误

  ErrorException in EventServiceProvider.php line 8:
 Declaration of 
 App\Providers\ 
 EventServiceProvider::boot(Illuminate\Contracts\Events\ Dispatcher $events) should be compatible with 
  Illuminate\Foundation\Support\Providers\EventServiceProvider::boot()

我尝试像这样从EventServiceProvider中删除参数

  /**
 * Register any other events for your application.
 *
 * @param  \Illuminate\Contracts\Events\Dispatcher  $events
 * @return void
 */
public function boot()
{
    parent::boot();

    //
}

更改前的EventServiceProvider：

  <?php

  namespace App\Providers;

  use Illuminate\Contracts\Events\Dispatcher as DispatcherContract;
  use Illuminate\Foundation\Support\Providers\EventServiceProvider as 
  ServiceProvider;

 class EventServiceProvider extends ServiceProvider
 {
/**
 * The event listener mappings for the application.
 *
 * @var array
 */
protected $listen = [
    'App\Events\SomeEvent' => [
        'App\Listeners\EventListener',
    ],
];
   /**
 * Register any other events for your application.
 *
 * @param  \Illuminate\Contracts\Events\Dispatcher  $events
 * @return void
 */
public function boot(DispatcherContract $events)
{
    parent::boot($events);

    //
}

   <?php

   namespace App\Providers;

   use Illuminate\Routing\Router;
   use Illuminate\Foundation\Support\Providers\RouteServiceProvider as 
   ServiceProvider;

  class RouteServiceProvider extends ServiceProvider
  {
/**
 * This namespace is applied to your controller routes.
 *
 * In addition, it is set as the URL generator's root namespace.
 *
 * @var string
 */
protected $namespace = 'App\Http\Controllers';


  /**
 * Define your route model bindings, pattern filters, etc.
 *
 * @param  \Illuminate\Routing\Router  $router
 * @return void
 */
public function boot(Router $router)
{
    //

    parent::boot($router);
}

更改前的RouteServiceProvider：

  <?php

  namespace App\Providers;

  use Illuminate\Contracts\Events\Dispatcher as DispatcherContract;
  use Illuminate\Foundation\Support\Providers\EventServiceProvider as 
  ServiceProvider;

 class EventServiceProvider extends ServiceProvider
 {
/**
 * The event listener mappings for the application.
 *
 * @var array
 */
protected $listen = [
    'App\Events\SomeEvent' => [
        'App\Listeners\EventListener',
    ],
];
   /**
 * Register any other events for your application.
 *
 * @param  \Illuminate\Contracts\Events\Dispatcher  $events
 * @return void
 */
public function boot(DispatcherContract $events)
{
    parent::boot($events);

    //
}

   <?php

   namespace App\Providers;

   use Illuminate\Routing\Router;
   use Illuminate\Foundation\Support\Providers\RouteServiceProvider as 
   ServiceProvider;

  class RouteServiceProvider extends ServiceProvider
  {
/**
 * This namespace is applied to your controller routes.
 *
 * In addition, it is set as the URL generator's root namespace.
 *
 * @var string
 */
protected $namespace = 'App\Http\Controllers';


  /**
 * Define your route model bindings, pattern filters, etc.
 *
 * @param  \Illuminate\Routing\Router  $router
 * @return void
 */
public function boot(Router $router)
{
    //

    parent::boot($router);
}

根据评论和讨论，您最终将Laravel框架更新到了5.3.31，这与5.2有着突破性的变化。解决方案可能是降级到5.2下的最新版本，或者按照升级指南将整个应用程序升级到5.3

要解决降级问题，请将
composer.json
中的当前框架包替换为
“laravel/framework”：“5.2.*”，
并运行
composer update
laravel的当前版本和以前版本（如果您记得的话）？同时发布完整的
EventServiceProvider.php
，更新后没有更改。我已经编辑了问题，请检查我需要查看完整的类，而不仅仅是引导方法。我可能知道问题是什么。我需要确认一下，对不起。我刚刚编辑了它。请检查您是否可以从
vendor/laravel/framework/src/illumb/Foundation/Application.php
检查框架版本并发布？它应该类似于
const VERSION='5.4.23'。从5.2分支的角度来看，我认为您的提供商没有任何问题。该解决方案工作得非常好。非常感谢。你救了我一天。
