Not compatible with spree 3.1.0

[krishruby]

Hello Team,

I am implementing my store using spree 3.1.0 and trying to add integrate spree_multi_tenant
getting below error -

Bundler could not find compatible versions for gem "spree_core":
  In snapshot (Gemfile.lock):
    spree_core (= 3.1.5)
  In Gemfile:
    spree (~> 3.1.0) was resolved to 3.1.5, which depends on
      spree_core (= 3.1.5)
