Unpacking gems and gem version numbers

I'm thinking about unpacking the gems that my app uses. If my development box has exactly the gem versions I want to unpack, do I still need to specify each gem's version in config/environment.rb?

config.gem "paperclip", :version => ''

Thanks for any help.

i think this is alway do,because rails instanse must check gem is install compelet.

rake freeze rails may resolved yours problem

If the versions installed on your dev machine are what you want, you won't need to specify the version. The gems:unpack code grabs whatever version is loaded when it's run. The versions in vendor/gems will be preferred regardless of what's installed on your production machine.

Thanks Matt. That's exactly what I wanted to confirm.
