当使用BitPay和Spree时，Bundler找不到与gem "railties“兼容的版本

Question

当我试着

bundle install

我得到了错误：

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)

我已经尝试了我的Gemfile的两个版本，一个是标准的Gemfile加上bitpay行，另一个是我注释掉了所有其他的Gemfile，只有bitpay行都不起作用。

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'

我刚接触Ruby和Gemfiles等。谢谢=)

做'gem list‘我可以看到我有两个必需的版本: railties (4.1.8，4.0.12，4.0.9，3.1.0)

这个问题的存在是因为spree-bitpay的gemspec只指定了'spree_auth_devise'，而他们在Gemfile中指定的版本实际上是这样的：

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

我怀疑当你使用bundle install时，它正在尝试使用Rubygems.org版本的spree_auth_devise，这个版本自2012年以来就没有更新过(似乎是在Rails 3的时候)。

您的问题的解决方案是添加到您的Gemfile以上行。

此外，您应该向spree-bitpay的维护者提出这个问题。请向他们开放一个问题，我相信他们会很感激的！
