Ruby on Mac OSX

In Mac, Ruby is preinstalled. You can open Terminal and input the followings to view the version of Ruby installed in your Mac

Update Ruby. You might want to update your Ruby, however there is no installer for Ruby like Windows. Instead, we can use MacPort.

Step 1. Install MacPort. You can download from their website: macports.org or DMG Image of Version 1.9.1 for Snow Leopard

Step 2. Open “Terminal” and input command:

sudo port

Step 3. MacPort should be started after inputting your password, then input command:

install ruby

It is easy, isn’t it? You can check what you have installed, you can input this command in MacPort:
