nodejs doesnt work with windows.

Here's how:

1) Install virtual box

2) Get an unbuntu iso

3) Install the ubuntu iso. For detailed instructions visit

4) Open a terminal on your ubuntu virtual machine.

5) Type in the following into your terminal to grab git and the build-essential packages

sudo apt-get install build-essential git-core

6) Type in the following into your terminal to grab node.js from git

git clone git://github.com/ry/node.git

7) Configure, make and install... type the following into your terminal:

./configure

make

make install

node.js is now installed on your machine.
