Bundler could not find compatible versions for gem "activesupport":
  In snapshot (Gemfile.lock):
    activesupport (4.0.0)

  In Gemfile:
    acts_as_commentable_with_threading (>= 0) ruby depends on
      activesupport (~> 3.0) ruby

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
