Installing Merb 1.0 on Mac OS X 10.5

My desktop development machine is a Mac (like most UNIX-bred developers these days). I’ll be using Merb as a web application framework for the yax.com project.

Merb needs Ruby 1.8.6, which is already available on Mac OS X 10.5.

Here’s how to check your Ruby version:

1. In iTerm, type ruby -v.
2. You should see “ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]“.

Check your version of RubyGems:

• gem -v

You’ll need RubyGems version 1.3.0 (or newer):

1. sudo gem install rubygems-update
2. sudo update_rubygems

Here’s how to install Merb:

• sudo gem install merb

And, since Merb is getting updated often, here’s how to update:

• sudo gem update merb
