I would continue explaining more about Node.js, but for all those folks who do things and understand them, here’s the way to install Node.js on Ubuntu machines..
You need to first install necessary packages like git-core and libssl-dev
sudo apt-get update sudo apt-get install g++ curl libssl-dev apache2-utils sudo apt-get install git-core
Download the latest source and build it
wget http://nodejs.org/dist/v0.8.2/node-v0.8.2.tar.gz gunzip node-v0.8.2.tar.gz tar xvf node-v0.8.2.tar.gz cd node-v0.8.2 ./configure sudo make install
Check the version after install
node -v
very useful
