I have 5 Rails 5 "canery apps’ that in the past run bundle cleanly, but yesterday things changed.
I have two repos (rt_demo_app5, rt_first_app5) that have run bundle cleanly (after adding rack
master to Gemfile) and 3 that do not (hello_app5, toy_app5, sample_app_5_0_rt) even after
adding the rack master to Gemfile.
For the ones that do not run bundle cleanly, the error message is (before adding rack master to Gemfile):
Bundler could not find compatible versions for gem "rack": In Gemfile: rails (>= 0) ruby depends on actionpack (= 5.0.0.alpha) ruby depends on rack (~> 2.x) ruby Could not find gem 'rack (~> 2.x) ruby', which is required by gem 'actionpack (= 5.0.0.alpha) ruby', in any of the sources.
Example Public repo: https://bitbucket.org/jasnow/sample_app_5_0_rt
I checked rubygems.org and latest rack is at 1.6.4 so unclear how to get 2.x.
So how do I change my Gemfile to find “rack 2.x”?
