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
``

[sourcecode language=”bash”]
ruby -v
[/sourcecode]

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:
``

[sourcecode language=”bash”]
sudo port
[/sourcecode]

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

[sourcecode language=”bash”]
install ruby
[/sourcecode]

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

[sourcecode language=”ruby”]
installed
[/sourcecode]
