And all this gems is installed, below is the list:

    spree_sample (3.1.1, 3.0.0)

I tried to install different version of rails, Spree, but always the same error. Could you please help?

Answer 1

You are trying to install spree with ~> 3.1.1 and spree_gateway '~> 3.0.0'.

This can be a dependency problem

Alternative option is

 gem 'spree'
 gem 'spree_gateway'

Put gem without specifying version

Execute:

 bundle install

Answer 2

You are trying to install spree with ~> 3.1.1 and spree_gateway '~> 3.0.0' . You have to change in your Gemfile spree_gateway version. Try

gem 'spree', '~> 3.1.1'
gem 'spree_gateway', '~> 3.1.0'

Answer 3

So I fallowed all your recommendations - removed versions from gemfile, removed all spree* excluding v3.0.0, only auth_devise is v3.1.0. Version of auth_devise 3.0.0 doesn't exist in repository I installed spree v3.1.0 for all the gem's to be the same version. Stil doesn't works A, below is the result:

Bundler could not find compatible versions for gem "spree_core":
  In Gemfile:
    spree (~> 3.0.0) was resolved to 3.0.0, which depends on
      spree_core (= 3.0.0)

    spree (~> 3.0.0) was resolved to 3.0.0, which depends on
      spree_core (= 3.0.0)

    spree (~> 3.0.0) was resolved to 3.0.0, which depends on
      spree_core (= 3.0.0)

    spree (~> 3.0.0) was resolved to 3.0.0, which depends on
      spree_core (= 3.0.0)

    spree (~> 3.0.0) was resolved to 3.0.0, which depends on
      spree_core (= 3.0.0)

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

Bundle update returns me this:

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    rails (>= 5.0.0.1, ~> 5.0.0)

    spree (~> 3.1.0) was resolved to 3.1.0, which depends on
      spree_core (= 3.1.0) was resolved to 3.1.0, which depends on
       rails (~> 4.2.6)

Answer 4

For now spree is not available for rails 5.0, so if you want to use it, you must go for rails 4.2.6(at least)

To create a project using an older version of rails just type: rails 4.2.6 new MyAppName

You can try this If works then fine otherwise use older version, as follow in the spree's README:

gem 'spree', github: 'spree/spree'

gem 'spree_auth_devise', github: 'spree/spree_auth_devise'

gem 'spree_gateway', github: 'spree/spree_gateway'
