Node js 项目启动报错,错误码,events.js:141,throw er; //Unhandled 'error' event,解决办法

 

当我遇到这个问题的时候,我纠结了好半天,找了好多资料,都说是端口占用,必须杀死端口重新启动,确实是这样。但是我当时在Windows下直接启动没有任何问题,直接就能把服务器启动起来,但是发现在mac下老是报这个错:

game server is listening on localhost:9003

client service is listening on port 9001

room service is listening on localhost:9002

events.js:141

     throw er; // Unhandled 'error' event

     ^

看到这些错误信息,我相信很多人都可能遇到过,也到处找解决办法,其实我们只要查看端口号,看看哪些端口被占用。

打开终端,然后输入:ps –ef|grep node,然后显示如图所示:

 Node js 项目启动报错,错误码,events.js:141,throw er; //Unhandled 'error' event,解决办法

Node js 项目启动报错,错误码,events.js:141,throw er; //Unhandled 'error' event,解决办法

 

 

我们会发现这几个文件占用了这几个端口,那么我们应该怎么办呢?当然是把这几个端口杀死,在终端输入:skill -9 1284,回车,然后再输入:skill -9 1288 ,继续输入skill -9 1858,回车,到此我们就把这几个端口占用都杀死了,如图所示:

 Node js 项目启动报错,错误码,events.js:141,throw er; //Unhandled 'error' event,解决办法

 

 

执行到这步,你再重新启动,应该就不会报错了,赶紧尝试吧!
