活动管理员安装错误

Question

尝试运行命令时出现错误：

rails g active_admin:install

错误是：

安装了活动管理员和设计 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，祝您有美好的一天。

Answer 1

您需要将gem 'devise' 添加到您的 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

为我工作。

gem 'devise', '~> 3.2'

Answer 3

activeadmin gem（我指的是 ruby​​gems.org 上最新版本的 gem）仍然与 Rails 4.x 不兼容。

尝试使用存储库中最新版本的 activeadmin：

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