So I went to Git Bash and typed npm install socket.io I found the the directory in my user folder: C:\Users\weka\node_modules... anyway, I dragged the socket.io folder into my project www folder because I am using WAMP server.

So, here's my server.js for testing: 

var app = require('express').createServer();
var io = require('socket.io').listen(app);

io.sockets.on('connection', function (socket) {
console.log('Someone connected!');
socket.on('set nickname' , function (nickname) {
socket.nickname = nickname;
console.log(nickname + ' just connected!');
});

});

app.listen(8080);

and I go into cmd and type node C:\wamp\www\gameTest\server.js

and I get the error that it cannot find the module called express. I thought I downloaded socket.io? I am a newb when it comes to GitHub.. so I probably did it wrong. :\

Help?

UPDATE: I found out I hadn't installed it. OK, I typed npm install express and I now I have express folder in my node_modules folder.

express and socket.io are different libraries. Just npm install express from the root of your app.

Also, make sure that your node dependencies are in a folder called node_modules - that's the convention used for module resolution. So, you should have a file structure that looks something like:

/some-app
    /node_modules
        /express
        /socket.io
    server.js

OK, just started server... it works. Thanks. – weka May 14 '12 at 18:50

The fix for me was to run npm at the root of your project. It installs the files relative to your project which is how node.js then looks for them to resolve the filename.
