我下载了官方的gatewayWorker的源码，保存到了本地，然后直接在根目录下执行如下命令：

php start.php start

结果报错，如下：

PHP Fatal error: Uncaught Error: Class 'GatewayWorker\BusinessWorker' not found in /root/Gateway/Applications/YourApp/start_businessworker.php:24
Stack trace:

另外我用phpstorm打开start_businessworker.php这个文件，头部提示如附件图片，代码有一个类没找到，另外有两个类用不上。
