Problem?

Rails used 3.2.22 4.2.0 4.2.4

appraisal in GemFile a gem 'rails', "3.2.22" working fine with all rails
appraisal in GemFile a gem 'rails', "~> 4.2" error:
 in Rakefile
  before load 'rails/tasks/engine.rake' Rails 3.2.22
  after  load 'rails/tasks/engine.rake' Rails 4.2.4

ENV['BUNDLE_GEMFILE'] may help?

==> ./test/dummy3/config/boot.rb:
  ENV['BUNDLE_GEMFILE'] ||= gemfile       # notice ||

wwtd --local OK
