Rake Not Finding Dependencies

Why would the file not be loaded? Any help is much开发者_如何学Python appreciated.

rake db:setup RAILS_ENV="development" --trace

   rake aborted!
   no such file to load -- rqrcode

/Users/dcarpenter/Dropbox/workspace/gems/barby-0.4.4/lib/barby/barcode/qr_code.rb:1:in `require'

Looks like you require 'rqrcode'. Maybe it's a missing gem that you need to install?
