tp5.1 运行workerman时出现 Cannot use WorkermanWorker as Worker because the name is already in use

错误原因：命名空间冲突

[thinkexceptionErrorException]                                          
Cannot use WorkermanWorker as Worker because the name is already in use

 解决办法：

找到目录：
vendor	opthink	hink-workersrccommandServer.php
 
找到命名空间：
use WorkermanWorker;
修改为：
use WorkermanWorker as Worker2;
紧接着修改 75,97,108, 119 行与 126的 worker 改为 Worker2
 
 
找到目录：
vendor	opthink	hink-workersrccommandGatewayWorker.php
 
找到命名空间
use WorkermanWorker;
修改为：
use WorkermanWorker as Worker3;
