title: How to skip bundle updates when doing migration?
body: <p>When I tried to create a new migration for db, the newest code forced me to do 'bundle install', but because of some network problem I cannot update the gems. Is there an option for migration I can skip updating bundles?</p>
  
  <pre><code>jimmy-mac:new_app jimmy$ rails g migration remove_title_from_offer
  
  Could not find webrat-0.7.3 in any of the sources
  Try running `bundle install`.
