Camaleon doesn't run in both rails 4.2.7 and with rails 5 ?

In rails 5
The problem is with breadcrumb_on_rails. Problem not solved.

In rails 4.2.7
/home/pradeep/adexchange/config/environments/development.rb:53:in block in <top (required)>': uninitialized constant ActiveSupport::EventedFileUpdateChecker (NameError) from /home/pradeep/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/railties-4.2.7/lib/rails/railtie.rb:210:ininstance_eval'

Please help

It was due to breadcrumb_on_rails gem. I solved it.
