已安装活动的admin和devise gem。 唯一的问题是当我生成活动管理员时。 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gem'devise gem 'devise'添加到Gemfile或直接使用cli

bundle add 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gem的最新版本）仍然与Rails 4.x不兼容。

尝试从存储库中使用使用最新版本的activeadmin：

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

Answer 3

为我工作。

gem 'devise', '~> 3.2'
