Finally after a lot of struggle i successfully installed Ruby On Rails which is commonly called (RoR).
1. Installed RVM ( Ruby Version Manager ).
2. Using that RVM installed Ruby and Gems.
3. Using that Gem installed Sqlite3 and Rails 3.0.1
Only three steps but i got lot of troubles installing it in my laptop.
There are lot of dependencies which should be checked post-installation of RVM via ” rvm notes “.
