Question

我试图使用ws包在node.js中构建p2p服务器但是在运行$HTTP_PORT=3002 P2P_PORT=5002 PEERS=ws://localhost:5004 npm run dev后我收到错误：

Listening on p2p port 5002
Listening on port 3002
events.js:165
      throw er; // Unhandled 'error' event
      ^

我尝试重新安装依赖项，更改端口，终止所有端口上的进程（3002,5002,5004），但它没有用。我相信有一些依赖性，我使用的是ubuntu 16.04节点9.11 / npm 5.6.0版本。

错误连接ECONNREFUSED websocket
