Node.js Socket.IO client 'unhandled socket.io url'

Question

I'm attempting to have a node.js client communicate with a node.js server using Socket.IO, according to the documentation this should be pretty easy however I'm just getting a message 'info - unhandled socket.io url' on the server whenever the clients tries to connect to the server. Here is a very basic example from the root:

---

in a directory I installed the necessary Socket.IO modules using:

npm install socket.io socket.io-client

in a file servernode.js I put:

var app = require('http').createServer(), io = require('socket.io').listen(app);
io.sockets.on('connection', function(socket) {
   console.log('connected');
});
app.listen(60000);

in another file clientnode.js I put:

var socket = require('socket.io-client')('http://localhost:60000');
socket.on('connect', function(){
     console.log('socket connected.');
});

in two terminals I put

node servernode.js

and

node clientnode.js

Then in the server I get this message repeated ad infinitum:

 info - unhandled socket.io url

---

I've searched for this message and from what I could gather, it was related to differences between versions, but I suppose npm has those modules synched, no? In desperation I also tried getting the file from the server module at './node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js' (and using .connect - somehow in this version it's necessary) but then I get another error:

/home/work/node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js:1877
var port = global.location.port ||
                          ^

Can anyone help me out with this?

Try using a newer version of socket.io, it worked for me.
