Q:

Impossible to deploy app in heroku - it searches ruby 2.0.0p195

I've deploying our app with rails 3.2.13 and ruby 2.0.0p0 without problems in heroku. However, today suddenly I couldn't deploy it. This is the log, it seems the only difference in our project is the version of ruby 2.0.0, which is trying to be installed:

       Could not find money-rails-0.8.0 in any of the sources
 !
 !     Failed to install gems via Bundler.

 !     Heroku push rejected, failed to compile Ruby/rails app

It seems that it cannot find the money-rails gem (version 0.8.0), but in localhost is working perfectly, and also until yesterday in heroku. I think it's has to be with the new ruby version as it's the only visible change regarding the gems...
Anyone with the same problem?
Thanks in advance!!

A:

You may not have changed anything but it appears the author of money-rails has yanked 0.8.0 and replaced it with 0.8.1. See http://rubygems.org/gems/money-rails for details.
You would have to do a bundle update and commit Gemfile.lock and redeploy and all should be good.
