Do I really have to install the bundler 1.0.0.beta.3 to run the latest edge rails?-Collection of common programming errors
On July 1st the Bundler dependency in edge Rails was bumped from 0.9.26 to 1.0.0.beta.2 (and each subsequent beta over the past weeks). As far as I know, edge Rails is still fully compatible with 0.9.26, so you should be able to edit rails.gemspec to read:
s.add_dependency('bundler', '>= 0.9.26')
I have already done this for 3 projects on edge rails, because they are deployed on Heroku which is still running Bundler 0.9.26. I’ve not had any issues or broken tests.
