Bundle Install very beginner problem

Question

Okay I'm basically day 1 at programming trying to follow Ruby On Rails 3 by Hartl... its not going well and I seem to be getting stuck every step of the way.

Right now I'm on page 19 & 20, not sure if I did it correct since it didn't really explain to well what it means but I get an error message. I did look thought other questions on here and didn't find any that were as beginner as mine that I might even understand.

For those without Hartl's book I found this page has it all: http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:the_first_application

So where it says to update the Gemfile I amended the document in TextMate to read gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'. The book then says:

Once you've assembled the proper Gemfile, install the gems using bundle install:

$ bundle install

Fetching source index for http://rubygems.org/

What I did was amend the file and just hit save, I'm not sure if that's what it means by assembling it or if there is something more I need to press. Looking through the menus in Textmate, nothing jumped out at me. When I then typed in bundle install I get the message unknown command bundle

Any advice in basic terms would be very helpful as I'm obviously a complete beginner at this. Thanks!

In order to use the bundler gem, you'll need to first install it.

gem install bundler

Then you can use:

bundle install
