Before installing rails, you need to install the ruby and rubygem.

Use “gem install rails” else you can update “gem update rails -V”, if installing for the first time.

-V is for verbose, it will show you what’s going on behind the screen. Also remember to use sudo before the command in ubuntu, mac os x. Otherwise it fails at the very end, very annoying.

•     if installing new rails
•     sudo gem install rails
•     if rails already present, and you want to update
•     sudo gem update rails -V
