Question

对于我的应用程序，我正在尝试将Ruby on Rails从版本3.2.13升级到4.0.0，我在安装/更新某些gem（使用Bundler）时遇到了麻烦，特别是{{ 3}}宝石。我正在运行Ruby 2.0.0-p247。

鉴于我的Gemfile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'

当我在终端窗口中运行bundle install命令时

然后我得到以下输出：

  In Gemfile:

    rails (4.0.0)

当我在终端窗口中运行bundle update命令时

然后我得到以下输出：

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？ globalize3 gem是否真的与Ruby on Rails 4兼容？是否可以等待升级到Ruby on Rails 4？

注意：我看到了globalize3 railscast，我在互联网上进行了很多搜索（最合理的讨论是“#415 Upgrading to Rails 4”）关于这个问题，但我是还有麻烦。

Answer 1

尝试使用rails4分支以避免升级问题。

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

但是，您可能仍会遇到一些问题，因为它不是稳定的分支。

Answer 2

globalize3 gem已重命名为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'
