RAILS：Bundler 在安装 ActiveAdmin 时找不到 gem "actionpack" 的兼容版本

Question

我在我的 gemfile 中添加了 gem 'activeadmin', github: 'activeadmin' 并进行了捆绑安装。然后它抛出以下错误。

Bundler could not find compatible versions for gem "actionpack":
   In snapshot (Gemfile.lock):
     actionpack (= 5.0.0.1)

In Gemfile:
activeadmin (~> 1.0.0.pre4) was resolved to 1.0.0.pre4, which depends on
  formtastic (~> 3.1) was resolved to 3.1.4, which depends on
    actionpack (>= 3.2.13)

activeadmin (~> 1.0.0.pre4) was resolved to 1.0.0.pre4, which depends on
  inherited_resources (~> 1.6) was resolved to 1.6.0, which depends on
    actionpack (< 5, >= 3.2)

activeadmin (~> 1.0.0.pre4) was resolved to 1.0.0.pre4, which depends on
  inherited_resources (~> 1.6) was resolved to 1.6.0, which depends on
    actionpack (< 5, >= 3.2)

activeadmin (~> 1.0.0.pre4) was resolved to 1.0.0.pre4, which depends on
  kaminari (~> 0.15) was resolved to 0.17.0, which depends on
    actionpack (>= 3.0.0)

activeadmin (~> 1.0.0.pre4) was resolved to 1.0.0.pre4, which depends on
  ransack (~> 1.3) was resolved to 1.8.2, which depends on
    actionpack (>= 3.0)

Running bundle update will rebuild your snapshot from scratch, using only the gems in your Gemfile, which may resolve the conflict.

我做了包更新，但错误还是一样。任何帮助将不胜感激。

gem 'activeadmin' is not compatible with rails 5

Answer 1

这个解决方案对我有用。对于 rails 5，您必须添加另一个 gem，如下所示：

gem 'activeadmin', github: 'activeadmin'
gem 'inherited_resources', github: 'activeadmin/inherited_resources'

要进一步阅读，请转到 this 话题。

Answer 2

您必须在 rails 5

中使用活动管理员安装继承资源 gem

gem 'activeadmin', github: 'activeadmin'
gem 'inherited_resources', github: 'activeadmin/inherited_resources'
