Anyone can help me figure it out?

Answer 1

If you have Leopard, you probably can use Ruby 1.8.7 with Rails 2.3.10.

Update your Ruby, and then

gem update --system

(or you might need to download RubyGems 1.3.7 from http://rubyforge.org/projects/rubygems/ unpack it, and run ruby setup.rb to get it)

After that, the commands can be

gem list
gem list -r rails
gem list -r rails$
gem list -rad rails$   <-- list all rails, with description, remotely
gem install haml
gem i fastercsv        <-- 'i' is a shorthand for install

gem i rails --no-rdoc --no-ri    <-- if you install a lot of gems by creating 
                                     different gemsets using RVM, and don't want 
                                     the docs every time

sudo gem i sqlite3-ruby          <-- on some systems, the sudo is needed, but if
                                     using RVM and you are not dealing with "system"
                                     gems, the recommendation is don't use "sudo"
