有关Mac Address already in use 端口占

listen(8002,'127.0.0.1');

1.在终端输入 sudo lsof -i:8002 这个端口

输入结果为

kill: 8002: No such process cyan@guanjiarendeMac day03 % sudo lsof -i:8002 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME node 12904 cyan 21u IPv4 0x4b45c8aacf8d688d 0t0 TCP localhost:teradataordbms (LISTEN)

2.sudo kill 12904 这样就好了

然后就可以重新跑起来了
