已安裝活動的admin和devise gem。 唯一的問題是當我生成活動管理員時。 我使用Rails-4.1.8和ruby-2.1.4。

感謝您的幫助和美好的一天。

Answer 1

您需要將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標志運行安裝。

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）仍然與Rails 4.x不兼容。

嘗試從存儲庫中使用使用最新版本的activeadmin：

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

Answer 3

為我工作。

gem 'devise', '~> 3.2'
