Ruby on rails 命名错误：未定义的方法`设计'；管理员

我已经安装了

设计gem

通过将其添加到gemfile并键入bundle 然后我打字

rails generate devise admin

我不能设计命名用户，因为我已经有用户了。 所以我犯了一个错误

NoMethodError: undefined method `devise' for Admin (call 'Admin.connection' to establish a connection):Class
/home/direwolf/rails_projects/unicom/app/models/admin.rb:4:in `<class:Admin>'
/home/direwolf/rails_projects/unicom/app/models/admin.rb:1:in `<top (required)>'
/home/direwolf/rails_projects/unicom/config/routes.rb:2:in `block in <top (required)>'
/home/direwolf/rails_projects/unicom/config/routes.rb:1:in `<top (required)>'

NoMethodError:Admin的未定义方法'designe'（调用'Admin.connection'建立连接）：类
/home/direwolf/rails\u projects/unicom/app/models/admin.rb:4:in`'
/home/direwolf/rails\u projects/unicom/app/models/admin.rb:1:in`'
/home/direwolf/rails\u projects/unicom/config/routes.rb:2:in'block in'
/home/direwolf/rails\u projects/unicom/config/routes.rb:1:in`'

我该怎么办？

您忘了运行生成器命令：

rails generate devise:install

---

这将加载所有设备配置选项。
