我有基于 ruby 2.7.1、rails 5.2、devise 4.7.2 和 activeadmin 2.9.0 构建的 rails 应用程序。我想将它更新到当前版本。当我将 ruby 更新到 3.2.1、rails 到 7.0、devise 到 4.9.2 和 activeadmin 到 2.13 时，我在 gem lib 文件 .rvm/gems/ruby-3.2.1/ 中得到了未初始化的常量 Devise::SessionsController gems/activeadmin-2.13.1/lib/active_admin/devise.rb:54:in module:Devise': 未初始化常量 Devise::SessionsController (NameError)

这是一个命名错误。 Active Admin 正在搜索它找不到的 SessionsController (extra s)。您应该检查会话的 Devise 控制器的命名。
也许你有
