Problem with Ruby on Rails with Rake

Question

I am very new to Rails, so please forgive my lack of understanding. I installed the latest versions of RubyGems, Ruby, Rails, Rake and MySQL, etc. Using RubyGems, but I had this problem when I started to build a basic Rails application:

Icarus:temporary atg$ rails new people
    ... (output omitted) ...
Icarus:temporary atg$ cd people
Icarus:people atg$ rake db:create
(in /Users/atg/temporary/people)
rake aborted!
uninitialized constant Bundler
/Users/atg/temporary/people/Rakefile:4
(See full trace by running task with --trace)
Icarus:people atg$ rake db:create --trace
(in /Users/atg/temporary/people)
rake aborted!
uninitialized constant Bundler
/Users/atg/.gem/ruby/1.8/gems/rake-0.8.7/lib/rake.rb:2503:in `const_missing'

/Users/atg/.gem/ruby/1.8/gems/rake-0.8.7/bin/rake:31
/usr/bin/rake:19:in `load'
/usr/bin/rake:19

I have no idea what I did wrong, and I'm so new to it that I don’t know that I could debug it if I had been working on it all my life - any ideas / guidance?

All help is appreciated and thanks in advance!

Bundler - Ruby Rails.

# ask rubygems to install bundler
$ gem install bundler

# ask bundler to install your app dependencies
$ bundle install

# run your app & tasks using bundler
$ bundle exec rake db:create

which ruby

from inside the shell and from inside the cron task. If you get different results, this indicates that the cron task does not work with the same ruby ​​as in the shell, and that the ruby ​​task performed by cron does not have a Bundler gem installed.
