如何修复 Laravel 在尝试广播新事件时抛出 FatalThrowableError

Question

我正在学习让 Laravel 实时广播的教程，但在跟随几分钟后就卡住了。Laravel 向我抛出以下消息“传递给 Illuminate\Database\Grammar::parameterize() 的参数 1 必须是数组类型，给定整数，在 /home/vagrant/code/vendor/laravel/framework/src/Illuminate 中调用/Database/Query/Grammars/Grammar.php 第 775 行“我已经多次尝试重做本教程以确保我没有遗漏任何内容，但多次尝试后问题仍然相同。即使检查堆栈跟踪和文档也没有给我任何线索。我已取消注释以下行config/app.php：App\Providers\BroadcastServiceProvider::class,我已将以下几行添加到App\Providers\EventServiceProvider：use App\Events\RideCreated;use App\Listeners\RideCreatedListener;以及protected $listen = [同一个文件中的以下内容    RideCreated::class => [        RideCreatedListener::class,    ],这是用于测试的路由设置 ( web.php)：Route::get('/test', function(){    event(new RideCreated());    return "test";});这是它的RideCreated.php样子：<?phpnamespace App\Events;use Illuminate\Broadcasting\Channel;use Illuminate\Queue\SerializesModels;use Illuminate\Foundation\Events\Dispatchable;use Illuminate\Broadcasting\InteractsWithSockets;use Illuminate\Contracts\Broadcasting\ShouldBroadcast;class RideCreated implements ShouldBroadcast{    use Dispatchable, InteractsWithSockets, SerializesModels;    /**     * Create a new event instance.     *     * @return void     */    public function __construct()    {        //    }    /**     * Get the channels the event should broadcast on.     *     * @return \Illuminate\Broadcasting\Channel|array     */    public function broadcastOn()    {        return new Channel('RideCreated');    }}
