Answer 1

I suppose you have in Gemfile

gem 'sprockets', '>= 2.2.1'
gem 'tilt', '2.0.0'

is tilt version 2.0.0 critical important? If it possible to downgrade it you can do following.

change in Gemfile

gem 'tilt', '1.4.1' # the previous version http://rubygems.org/gems/tilt

run

bundle update tilt

After this you can remove tilt version from Gemfile
