Node.js w / socket.io: TypeError: Obj does not have a 'on' method in the new dispatcher

Question

Following the lead here and encountering difficulties.

I installed socketIO with npm install socket.io When I start node server.js , the following exception is thrown:

 node.js:134 throw e; // process.nextTick error, or 'error' event on first tick ^ TypeError: Object #<Object> has no method 'on' at new Manager (/Users/x/nodeprojects/cloudnode/node_modules/socket.io/lib/manager.js:97:10) at Object.listen (/Users/x/nodeprojects/cloudnode/node_modules/socket.io/lib/socket.io.js:71:10) at Object.<anonymous> (/Users/x/nodeprojects/cloudnode/sky/server.js:12:26) at Module._compile (module.js:402:26) at Object..js (module.js:408:10) at Module.load (module.js:334:31) at Function._load (module.js:293:12) at Array.<anonymous> (module.js:421:10) at EventEmitter._tickCallback (node.js:126:26) 

server.js:

 var static = require('./plugins/node-static'); var socketIO = require('socket.io'); var clientFiles = new static.Server('./client'); var httpServer = require('http'); httpServer.createServer(function (request, response) { request.addListener('end', function () { clientFiles.serve(request, response); }); }).listen(8253); var webSocket = socketIO.listen(httpServer); webSocket.on('connection', function(client) { client.send('Please enter a user name ...'); var userName; client.on('message', function(message) { if(!userName) { userName = message; webSocket.broadcast(message + ' has entered the zone.'); return; } var broadcastMessage = userName + ': ' + message; webSocket.broadcast(broadcastMessage); }); client.on('disconnect', function() { var broadcastMessage = userName + ' has left the zone.'; webSocket.broadcast(broadcastMessage); }); }); 

I am running node v 0.4.10 Does anyone have an idea for a solution?

You are passing the http module to socket.io instead of the http server.

 var http = require('http'); var httpServer = http.createServer(function (request, response) { request.addListener('end', function () { clientFiles.serve(request, response); }); }).listen(8253); var webSocket = socketIO.listen(httpServer); webSocket.on('connection', function(client) {
