Do I really have to install the bundler 1.0.0.beta.3 to run the latest edge rails?

When I do bundle install bundling edge rails I get this error:

No compatible versions could be found for required dependencies:
    Conflict on: "bundler":
    * bundler (0.9.26) activated by bundler (= 0.9.26开发者_StackOverflow中文版, runtime)
    * bundler (>= 1.0.0.beta.3, runtime) required by rails (>= 0, runtime)
    All possible versions of origin requirements conflict.

Is there any way that I can install the lastest edge rails without installing bundler 1.0.0.beta.3?

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.
