我尝试使用 rails_admin 的示例初始化程序将 piggybak 集成到我的 rails 应用程序中
https://github.com/piggybak/demo/blob/master/config/initializers/rails_admin.rb
当我尝试启动服务器时，出现以下错误：
/home/dumand/Desktop/Projects/3dgreen/config/initializers/rails_admin.rb:32:in nestable block (2 levels) in <top (required)>': undefined method' 用于 RailsAdmin::Config::Actions:Module (NoMethodError)
这是服务器日志：

这是 rails_admin 初始化程序：
RailsAdmin.config do |config|
config.main_app_name = ["3D Green"]
