安装了主动管理和设计宝石。唯一的问题是我生成活动管理员。我使用Rails-4.1.8和ruby-2.1.4。

感谢您的帮助和美好的一天。

Answer 1

您需要将devise gem添加到您的Gemfile

gem 'devise'

或者您需要使用--skip-users标志运行安装。

rails g active_admin:install --skip-users

Answer 2

activeadmin gem（我的意思是rubygems.org上的最新版本的gem）仍然与Rails 4.x不兼容。

尝试使用来自存储库的最新版本的activeadmin：

gem 'activeadmin', github: 'activeadmin/activeadmin', branch: :master

Answer 3

适合我。

gem 'devise', '~> 3.2'
