Rails Installation

Ruby must be installed for rails installation.

Check for gem installation by typing gem --version in a command window.

Now we will use RubyGems to install Rails.

Check whether your internet connection is active.

In a command window, type gem install rails --include-dependencies

Now you are ready to run rails(RoR).

To update your rails application, simply type gem update rails in command window. This will automatically update your rails installation.

Getting Started with a New Rails Application

1. Create new Rails application by the command rails , like c:\>rails demo


2. This will automatically create rails application name ‘demo’ with standard directory structure.


3. Change directory to c:\>cd demo, then Start WEBrick server by the command c:\demo>ruby script/server . Then access http://localhost:3000/ in the browser, you should see a screen that looks like this.





4. This confirms that the installation was successful and Rails is running.
