节点红色throwinr突然错误

Question

无法理解错误。工作到昨天。

Error: connect ECONNREFUSED 127.0.0.1:8080
    at Object.exports._errnoException (util.js:870:11)
    at exports._exceptionWithHostPort (util.js:893:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1063:14)

netstat -ntlo |的输出grep LISTEN

tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      -
