从 4.2.0 更新到 5.0.2 的问题

Question

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    active_model_serializers (~> 0.10.0.rc5) was resolved to 0.10.9, which depends on
      actionpack (>= 4.1, < 6)

    axlsx_rails (~> 0.5.0) was resolved to 0.5.2, which depends on
      actionpack (>= 3.1)

    haml-rails was resolved to 1.0.0, which depends on
      actionpack (>= 4.0.1)

    rails (= 5.0.2) was resolved to 5.0.2, which depends on
      actionpack (= 5.0.2)

    responders (~> 2.0) was resolved to 2.4.1, which depends on
      actionpack (>= 4.2.0, < 6.0)

    rspec-rails (~> 3.0) was resolved to 3.8.2, which depends on
      actionpack (>= 3.0)

Bundler could not find compatible versions for gem "activerecord":
  In Gemfile:
    activerecord-postgis-adapter (~> 3.1.4) was resolved to 3.1.5, which depends on
      activerecord (~> 4.2)

    rails (= 5.0.2) was resolved to 5.0.2, which depends on
      activerecord (= 5.0.2)

Bundler could not find compatible versions for gem "rails":
  In Gemfile:
    rails (= 5.0.2)

    leaflet-rails was resolved to 1.5.1, which depends on
      rails (>= 4.2.0)

    react-rails (~> 1.6.0) was resolved to 1.6.2, which depends on
      rails (>= 3.2)

Bundler could not find compatible versions for gem "resque":
  In Gemfile:
    resque (~> 1.26.0)

    resque-scheduler (~> 4.3.0) was resolved to 4.3.1, which depends on
      resque (~> 1.26)

我将文件“GemFile”更改为 5.0.2 并出现错误。该错误并未说明任何 gem 不支持 5.0.2。请帮帮我。 更新原因：

我尝试了很多方法来解决这个问题，但没有任何帮助。有没有人遇到过类似的情况并且知道解决这个问题的方法。

Rails 4.2.0

Answer 1

啊，老 Rails 主要版本的碰撞任务。

看起来您的许多 Gem 都在您的 Gemfile 中设置了特定版本。单独更改 rails gem 版本是行不通的，你会得到很多依赖错误，更糟糕的是，这只是一个开始 - 很多其他事情以后可能会变坏。

您可以从所有 gem 中删除版本，然后将 rails 设置为 5.2 或其他任何版本，然后在它们弹出时解决依赖错误。预计这是一个漫长的过程，显然不要在生产机器上进行。

您甚至可能需要或发现在某些情况下更方便地将更新应用到基础服务（例如数据库）。

如果您没有任何规范/测试，您将想要测试整个应用程序，或者开始编写它们。

您在 Gemfile 中更改后是否运行 bundle install？不建议直接升级到Rails 5.2..首先使其稳定并在rails 5.0中运行，然后在5.1中运行
