Three Ways of Installing Ruby

1 Compiling Ruby - Source code
2 Third Party Tools
3 Package Management Systems

Compiling Ruby - Source code

Installing from the source code is a best solution. In case you are comfortable enough with your platform and perhaps need specific settings for your environment. It's also a good solution in the event that there are no other pre-made packages for your platform. You can optimise the build for your need for you suitable platform.

Third Party Tools

The community members maintains the tool to help other to install ruby. They provide various other advantages to users. Also they are very helpful to find solutions. Following are the popular third-party tools to install Ruby.

RVM  

"Ruby Version Manager." Not only does it make installing Ruby incredibly easy, it also allows you to install and manage multiple copies of Ruby on your system, as well as multiple alternate implementations of Ruby. RVM is available for Mac OS X, Linux, or any UNIX-like operating system. Windows users should check out pik (https://github.com/vertiginous/pik) for a similar project.

Package Management Systems

If you can't compile your own Ruby, and you don't want to use a third party tool, you can use your system's package manager to install Ruby.  Most package managers have older versions of Ruby in their repositories. If you'd like to use the newest Ruby, make sure you use the correct package name, or use any third-party tools.

Linux 

Debian GNU/Linux uses the apt package manager system. (So does Ubuntu.) You can use it like this:
sudo apt-get install ruby1.9.1
This will install Ruby 1.9.2. It has a 'library compatibility version' of 1.9.1, hence the name.

Mac OS X

Ruby 1.8.7 is fully supported in Mac OS X Lion as well as many popular Ruby gems (packages)
Many people on Mac OS X use Homebrew (http://mxcl.github.com/homebrew/) as a package manager. It's really easy to get Ruby:
brew install ruby
