对于我的应用程序，我正在尝试将 Ruby on Rails 从版本升级3.2.13到4.0.0并且在安装/更新某些 gem（通过使用 Bundler）时遇到麻烦，特别是globalize3 gem。我正在运行 Ruby 2.0.0-p247。

鉴于我Gemfile的是：

gem 'rails', '4.0.0'

gem 'globalize3', github: 'svenfuchs/globalize3', branch: 'rails4'

gem 'delayed_job', :git => 'git://github.com/collectiveidea/delayed_job.git', :branch => 'master'
gem 'delayed_job_active_record', :git => 'git://github.com/collectiveidea/delayed_job_active_record.git', :branch => 'master'

# Added these gems to help with the transition to rails4:
gem 'protected_attributes'
gem 'rails-observers'
gem 'actionpack-page_caching'
gem 'actionpack-action_caching'
gem 'activerecord-deprecated_finders'

当我bundle install在终端窗口中运行命令时

然后我得到以下输出：

    delayed_job_active_record (>= 0) ruby depends on
      activerecord (4.0.0)

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    globalize3 (>= 0) ruby depends on
      rails (~> 3) ruby

    rails (4.0.0)

当我bundle update在终端窗口中运行命令时

然后我得到以下输出：

    rails (4.0.0)

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    globalize3 (>= 0) ruby depends on
      railties (~> 3.0) ruby

    coffee-rails (~> 4.0.0) ruby depends on
      railties (4.0.0)

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    rails (= 4.0.0) ruby depends on
      actionpack (= 4.0.0) ruby

    actionpack-action_caching (>= 0) ruby depends on
      actionpack (4.0.0.rc2)

我该如何解决这个问题？gem真的globalize3与 Ruby on Rails 4 兼容吗？等待升级到 Ruby on Rails 4 是否可取？

注意：我看到了#415 Upgrading to Rails 4 railscast 并且我在互联网上进行了很多搜索（最合理的讨论是“ Globalize3 does not work with Rails4 ”），但我仍然遇到了麻烦。

尝试使用 rails4 分支来避免升级问题。

gem 'globalize3', git: 'https://github.com/svenfuchs/globalize3.git', branch: 'rails4'

但是，您可能仍然会遇到一些问题，因为它不是稳定的分支。

globalize3gem 已重命名，globalize主要版本号现在对应于 ActiveRecord 的相应版本（AR3 为 3.x，AR4 为 4.x）。

所以你需要做的就是把它放在你的 Gemfile 中，你不应该有任何冲突：

gem 'globalize', '~> 4.0.0.alpha.2'

另请参阅github 存储库以获取更多详细信息。
