我按照本教程在ubuntu上安装node.js,安装成功。但是当我输入节点echo-server.js时,我收到以下错误:
module.js:340
throw err;
^
Error: Cannot find module '../../lib/ws/server'

回显服务器代码:
var sys = require("util")
, ws = require('../../lib/ws/server');
var server = ws.createServer({debug: true});
// Handle WebSocket Requests
server.addListener("connection", function(conn){
conn.send("Connection: "+conn.id);
conn.addListener("message", function(message){
conn.send("<"+conn.id+"> "+message);
if(message == "error"){
conn.emit("error", "test");
}
}); });
server.addListener(“error”,function(){ console.log(Array.prototype.join.call(arguments,“,”)); });
server.addListener(“disconnected”,function(conn){ server.broadcast(“&lt;”+ conn.id +“&gt; disconnected”); });
server.listen(8000);
但缺少lib / ws / server。但是我从哪里得到它? 我猜我的node.js安装中没有Web套接字服务器。
