使用BitPay和Spree Commerce时，Bundler找不到与宝石“铁路”兼容的版本

Question

When I try to

bundle install

I get the error:

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    spree_bitpay (>= 0) ruby depends on
      spree_auth_devise (>= 0) ruby depends on
        devise (~> 2.0.4) ruby depends on
          railties (~> 3.1) ruby

    spree_bitpay (>= 0) ruby depends on
      rails (= 4.0.9) ruby depends on
        railties (4.0.9)

I have tried 2 versions of my Gemfile, one where I have the standard Gemfile plus the bitpay line, and one where I have all other gems commented out, and just the bitpay line, neither work.

Gemfile:

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.9'

# Use sqlite3 as the database for Active Record
gem 'sqlite3'

# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.2'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]
gem 'spree_bitpay', :git => 'https://github.com/bitpay/spree-bitpay.git'

I'm new to Ruby, and Gemfiles etc. Thanks =)

Doing 'gem list' I can see that I have both required versions: railties (4.1.8, 4.0.12, 4.0.9, 3.1.0)

The problem exists because spree-bitpay's gemspec only specifies 'spree_auth_devise', while the version that they're specifying in their Gemfile is actually as such:

gem 'spree_auth_devise', :git => 'https://github.com/spree/spree_auth_devise.git', :branch => '2-2-stable'

I suspect that when you bundle install , it's attempting to use the Rubygems.org version of spree_auth_devise, which has not been updated since 2012 (seems to be around the time of Rails 3).

The solution to your problem is to add to your Gemfile the above line.

Furthermore, you should bring up this issue with the maintainers of spree-bitpay. Please open an issue with them, I'm sure they'll appreciate it!
