Beanbun整合到yii2框架时，无法运行

[aaronlei]

use yii\console\Controller;
use Beanbun\Beanbun;

class DemoController extends Controller
{

    public function actionBeanbun()
    {
        $beanbun = new Beanbun();
        $beanbun->seed = [
            'http://www.950d.com/',
            'http://www.950d.com/list-1.html',
            'http://www.950d.com/list-2.html',
        ];
        $beanbun->afterDownloadPage = function ($beanbun) {
            file_put_contents(__DIR__ . '/' . md5($beanbun->url), $beanbun->page);
        };
        $beanbun->start();
    }
}

问题一

PHP Notice 'yii\base\ErrorException' with message 'Undefined property: Beanbun\Beanbun::$count'
in /xxx/vendor/kiddyu/beanbun/src/Beanbun.php:136

问题二
在Beanbun加上count属性后，发现依然不能工作

会一直提示

Usage: php yourfile.php {start|stop|restart|reload|status|connections} [-d]
