how to install old version of express.js

How do I install the right version of express and do I have to uninstall 3.x before I install 2.x?

This is the tutorial I am trying to test: http://psitsmike.com/2011/09/node-js-and-socket-io-chat-tutorial/

I used this package.json:

{
     "name": "mukhin_chat",
     "description": "example chat application with socket.io",
     "version": "0.0.1",
     "dependencies": {
        "express": "2.4.6",
        "socket.io": "0.8.4"
     }
}

and used the following command: 

npm install -d

When I run the app I still get the question: ... are you migrating from Express 2.x to 3.x ...

This is pretty easy, to remove the current version of express, just type

npm uninstall express

Followed by the following command to install a specific version of a package:

npm install [email protected]
