I tried Pasha's suggestion, but it looks like the environment variable is ignored by bundler in heroku.
I added autotest-fsevent to the :development group in my gemfile, and added BUNDLE_WITHOUT=test:development to the heroku app config. But when I pushed, heroku still tried to build the native extensions and failed. I don't understand why heroku doesn't just use "bundle install -- deployment" (or some variation) to respect the Gemfile groups... I got another idea. Hide autotest-fsevent from Heroku by using :platforms. According to the bundler docs the platform is respected automatically. Unfortunately they don't have an "OSX" platform, so I randomly chose one that doesn't match Heroku just to test. platforms :mswin do gem "autotest-fsevent" end It worked! The gem was not installed and the push succeeded. The next step would be to hack my local bundler to make it think I'm on :mswin (or :jruby), so that the gem gets picked up locally. Important note: only the block version of :platform works due to a bug: http://github.com/carlhuda/bundler/issues#issue/590 -- You received this message because you are subscribed to the Google Groups "Heroku" group.
