我一直在尝试将我的 Rails 应用程序从 5.1.0rc1 迁移到 5.1.0。

这是我的宝石文件：

gem 'rails', '~> 5.1.0'
gem 'mysql2', '>= 0.3.18', '< 0.5'
gem 'puma', '~> 3.0'
gem 'sass-rails', '~> 5.0'
gem 'turbolinks', '~> 5'
gem 'uglifier', '>= 1.3.0'
gem 'redis', '~> 3.3.3'
gem 'redis-rails', '~> 5.0.1'
gem 'jbuilder', '~> 2.5'
gem 'sidekiq', '~> 4.2.10'
gem 'active_model_serializers', '~> 0.10.5'
gem 'jwt', '~> 1.5.6'
gem "mini_magick", '~> 4.7.0'
gem 'rack-cors', "~> 0.4.1"
gem 'mandrill-api', "~> 1.0.53"
gem 'curb', "~> 0.9.3"
gem 'inherited_resources', '~> 1.7'
gem 'activeadmin', '~> 1.0.0'
gem 'coffee-rails', '~> 4.2.1'
gem 'therubyracer', git: 'https://github.com/cowboyd/therubyracer.git'
gem 'meta-tags', '~> 2.4.0'
gem 'slim', '~> 3.0.7'

这是我从捆绑安装中得到的：

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    active_model_serializers (~> 0.10.5) was resolved to 0.10.5, which depends on
      actionpack (< 6, >= 4.1)

    activeadmin (~> 1.0.0) was resolved to 1.0.0, which depends on
      formtastic (~> 3.1) was resolved to 3.1.5, which depends on
        actionpack (>= 3.2.13)

    activeadmin (~> 1.0.0) was resolved to 1.0.0, which depends on
      inherited_resources (~> 1.7) was resolved to 1.7.0, which depends on
        actionpack (< 5.1, >= 3.2)

    rails (~> 5.1.0) was resolved to 5.1.0, which depends on
      actionpack (= 5.1.0)

    rails (~> 5.1.0) was resolved to 5.1.0, which depends on
      actionpack (= 5.1.0)

    rails (~> 5.1.0) was resolved to 5.1.0, which depends on
      actionpack (= 5.1.0)

    activeadmin (~> 1.0.0) was resolved to 1.0.0, which depends on
      ransack (~> 1.3) was resolved to 1.8.2, which depends on
        actionpack (>= 3.0)

有什么问题？

如果有帮助（但我对此表示怀疑），我会在 Docker 容器上工作。我已删除Gemfile.lock以避免冲突。

这里有问题的 gem 是activeadmin's ，当你问你的问题时inherited_resources指定了它的最新版本。actionpack (< 5.1, >= 3.2)

也许令人惊讶的是，您之前的 actionpack 候选版本5.1.0.rc1满足< 5.1约束条件，因此您没有被阻止升级到候选发布版本，而是被阻止进入最终版本。

新版本inherited_resources于 5 月 3 日被删除，它将修复一些问题，但请注意当前的gemspec意味着当 Rails 进入 5.2 时您将遇到同样的问题。
