can not install .

I saw the grape-reload.gemspec file:
spec.add_runtime_dependency "rack", ">= 1.5.2"
but when i install this gem. it tell me :
In snapshot (Gemfile.lock):
rack (= 1.6.4)

In Gemfile:
grape (>= 0) ruby depends on
rack (>= 1.3.0) ruby

grape (>= 0) ruby depends on
  rack-accept (>= 0) ruby depends on
    rack (>= 0.4) ruby

grape (>= 0) ruby depends on
  rack-mount (>= 0) ruby depends on
    rack (>= 1.0.0) ruby

grape-reload (>= 0) ruby depends on
  rack (~> 1.5.2) ruby

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