title: Command not found/Install missing gem binaries with 'bundle install' using autotest
body: <p>I am totally new to RoR. I am following Michael Hartl's book. I am not able to make autotest run. Please suggest what's going wrong and a solution to fix it.</p>
  
  <p>When I run 'autotest' at command line inside Rails project directory i get following:</p>
  
  <pre><code>-bash: autotest: command not found
  </code></pre>
  
  <p>When I run 'bundle exec autotest' I get following:</p>
  
  <pre><code> bundler: command not found: autotest
   Install missing gem binaries with `bundle install'
  </code></pre>
  
  <p>Here is the Gemfile</p>
  
  <pre><code>source 'http://rubygems.org'
  
  gem 'rails', '3.0.3'
  gem 'sqlite3-ruby', :require =&gt; 'sqlite3'
  
  group :development do
  gem 'autotest'
  gem 'rspec-rails', '2.4.1' 
  end
  
  group :test do
  gem 'rspec', '2.4.0'
  gem 'webrat', '0.7.1'
  end
