Composer update打破了Laravel 5.2网站

Question

我不小心运行了打破我网站的作曲家更新。我正在使用Laravel 5.2。现在，我收到此错误

  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()

我尝试从此事件中删除EventServiceProvider中的参数

  /**
 * 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);

    //
}

来自RouteServiceProvider.php

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

    parent::boot();
}

更改前的RouteServiceProvider：

   <?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);
}

现在，我收到此错误：       Macroable.php第74行中的BadMethodCallException：       方法控制器不存在。

请帮帮我。谢谢。

根据评论和讨论，您以某种方式最终将Laravel框架更新为5.3.31，其中包含5.2的突破性更改。解决方案是降级到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。

要使用降级功能进行修复，请使用composer.json替换"laravel/framework": "5.2.*",中的当前框架包并运行composer update
