Getting error during bundle

[w3villa-amit]

Hello i am trying to add the gem 'spree_active_shipping', github: 'spree-contrib/spree_active_shipping',branch: '3-1-stable' and after doing bundle i got -: Bundler could not find compatible versions for gem "spree_core": In snapshot (Gemfile.lock): spree_core (= 3.4.5)

In Gemfile: spree (~> 3.4.0) was resolved to 3.4.5, which depends on spree_core (= 3.4.5)

spree_active_shipping was resolved to 3.1.0, which depends on
  spree_core (~> 3.1.0.beta)

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

and my gemfile is -: source 'https://rubygems.org' ruby '2.3.1'

git_source(:github) do |repo_name| repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/") "https://github.com/#{repo_name}.git" end
