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

     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：

 

 

 

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：

 

 

 

执行到这步，你再重新启动，应该就不会报错了，赶紧尝试吧！
