Bundler could not find compatible versions for gem "sprockets-rails", rails 4.2 master

[Fudoshiki]

Bundler could not find compatible versions for gem "sprockets-rails":
In Gemfile:
sass-rails (>= 0) ruby depends on
sprockets-rails (~> 2.0) ruby

rails (>= 0) ruby depends on
sprockets-rails (3.0.0.beta1)
Need new gemspec for sprockets >= 2.8

need fix for commit 40cd1d4

also need fix sass-rails.gemspec in rails/sass-rails

s.add_dependency 'sprockets-rails', '> 2.0'
s.add_dependency 'sprockets', '> 2.12'

[rafaelfranca]

Try now please. Make sure of adding the sass-rails version on the Gemfile. It need to be 5.0.0.beta1

finlay I got sprockets 2.12, but need beta 3.0
rails s failing with
bin/rails:6: warning: already initialized constant APP_PATH
bin/rails:6: warning: previous definition of APP_PATH was here
coz wrong sprockets gem

[Fudoshiki]

s.add_dependency 'sprockets', '~> 2.12'
fix this in sass-rails.gemspec

[rafaelfranca]

sprockets 3.0 beta is not supported yet.

[rafaelfranca]

This is exactly what we have there https://github.com/rails/sass-rails/blob/master/sass-rails.gemspec#L21

[Fudoshiki]

sass 4.0 in master branch
sass-rails.gemspeck ~> 3.2

Could not find gem 'sass (~> 3.2) ruby', which is required by gem 'sass-rails (>= 0) ruby', in any of
the sources.

with sprockets 2.12 rails s fails

[rafaelfranca]

sass 4 is also not supported. rails s is working fine in a new application.

[Fudoshiki]

changed master branch gem 'sprockets', github: 'sstephenson/sprockets' on gem 'sprockets', github: 'sstephenson/sprockets', branch: '2.x'
fixed rails s
done
