  Installing Rails 3 on Mac OS X Snow Leopard

  … should be as simple as typing

  sudo gem install rails --pre
  

  in your Terminal. If something doesnt work with the database, try:

  sudo gem install sqlite3-ruby
  

  you are now ready to generate a new rails app by typing

  rails new myapp
  cd myapp
  

  test it by starting the server

  rails server
  

  go to http://localhost:3000 in your browser and click "About your application's environment" now you should see something like this:

  Ruby version      1.9.2 (x86_64-darwin10.4.0)
  RubyGems version  1.3.7
  Rack version      1.1
  Rails version     3.0.0.beta4
  ...
  

  Using Mongrel with Rails 3

  install mongrel by typing

  gem install mongrel --pre
  

  then add to the Gemfile in your Rails 3 Appliation:

  gem 'mongrel', '1.2.0.pre2'
  

  and in your application folder try

  rails server
  

  now it should say

  <div>=> Booting Mongrel</div>
  => Rails 3.0.0.beta4 application starting in development on http://0.0.0.0:3000
  => Call with -d to detach
  => Ctrl-C to shutdown server
  ...
