Environment for Rails 3

Today, I like to create a new rails 3 application from scratch.

First, i need to setup a new environment. RVM is a handy tool to manage ruby environment for rubygems to gemset. My PC has RVM already installed, the next step would be installing ruby (current stable version of ruby is 1.9.2) and rails 3.

rvm install 1.9.2
rvm use 1.9.2
gem install bundler
gem install rails
