php - 找不到 Laravel/Dusk Swift_Events_EventListener

Question

Laravel 框架 5.4.13

基本上我正在使用 video tutorial

但是当我在视频中播放到 4:30 时，出现此错误:

Fatal error: Interface 'Tests\Browser\Swift_Events_EventListener' not found in C:\xampp\htdocs\XXX\tests\Browser\MailTracker.php on line 46 PHP Fatal error: Interface 'Tests\Browser\Swift_Events_EventListener' not found in C:\xampp\htdocs\XXX\tests\Browser\MailTracker.php on line 46

代码:

<?php

namespace Tests\Browser;

use App\User;
use Tests\DuskTestCase;
use Laravel\Dusk\Chrome;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Tests\TestCase;

class MailTracker extends DuskTestCase
{
    public function SetUp()
    {
        parent::SetUp();

        Mail::getSwiftMailer()
            ->registerPlugin(new TestingMailEventListener);
    }
    /**
     * A basic browser test example.
     *
     * @return void
     */
    public function testBasicExample()
    {
        Mail::raw('Hello', function ($message){
            $message->to('foo@bar.com');
            $message->from('bar@foo.com');
        });
    }

    protected function seeEmailWasSent()
    {

    }
}

class TestingMailEventListener implements Swift_Events_EventListener
{
    public function beforeSendPerformed($event)
    {
        $message = $event->getMessage();
        dd($message);
    }
}

知道是什么导致了这个问题吗？

添加:

use Swift_Events_EventListener;

解决问题，就这么简单。
