- Bundler + Heroku gotcha: Deploys to Heroku can break if you are using Bundler v1.0.6 in your local development environment (as of this writing, Heroku is using v1.0.3). Apparently the
--deploymentswitch is being stripped off andGemfile.lockis rebuilt. If the file differs from what's in the git repository, the deploy will fail with a somewhat mysterious error message. Work-around: Specify the bundler gem version to v1.0.3 (perhaps even up to v1.0.5) in yourGemfile.
