【解决办法】

　　由于被占用的端口是 22346，已是2万多的端口号，不太可能被其他人的其他程序占用。因此，可能是自己上一个进程跑完没有结束导致当前进程端口被占用。

因此，只需要在执行完程序之后，（跑完工程之后），用命令杀掉端口的程序即可。

macOS 系统在终端使用命令查看并杀除进程：

##  查看使用 端口 22346 的进程

➜  ~ lsof -i:22346

COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME

node    55576 user   21u  IPv4 0x572d0cec2a30c695      0t0  TCP localhost:22346 (LISTEN)

##  杀掉使用appium的进程

➜  ~ ps -ef |grep 'appium'|grep -v 'grep'| awk '{print $2}'| xargs kill -2    （其实用这个即可）

##  杀掉PID为55576的进程

➜  ~ kill -9 55576

kill: kill 55576 failed: no such process
