Grunt Server:Fatal error: Port 35729 is already in use by another process.

提示35729端口被占用，使用lsof命令进行查看：

y@y:yo-test$ lsof -i :35729

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

ionic   23071    y   14u  IPv6 230518      0t0  TCP localhost:35729->localhost:48009 (ESTABLISHED)

35729被ionic测试项目占用，把ionic项目停止后就可以了。
