Class 'PushManager' 未找到 - Laravel 4.2

Class 'PushManager' not found - Laravel 4.2

我正在 laravel 4.2 并且正在尝试安装 https://github.com/Ph3nol/NotificationPusher

安装的很好但是我运行进入错误:

Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_UNKNOWN)
Class 'PushManager' not found

当我运行 /push 路由如下:

Route::get('push', function(){
    // First, instantiate the manager and declare an adapter.
    $pushManager    = new PushManager();
    $exampleAdapter = new ApnsAdapter();

    // Set the device(s) to push the notification to.
    $devices = new DeviceCollection(array(
        new Device('Token1'),
        new Device('Token2'),
        new Device('Token3'),
        // ...
    ));

    // Then, create the push skel.
    $message = new Message('This is an example.');

    // Finally, create and add the push to the manager, and push it!
    $push = new Push($exampleAdapter, $devices, $message);
    $pushManager->add($push);
    return $pushManager->push();
});

我可以错过一步吗? (也许在我的 app.php 中声明提供者或别名)

routes.php 的顶部添加以下内容:

use Sly\NotificationPusher\PushManager;
use Sly\NotificationPusher\Adapter\Apns as ApnsAdapter;

路由在全局命名空间中定义,PushManager存储在另一个命名空间中,因此需要显式导入。
