Rails 6：如何禁用操作邮箱和操作文本加载到内存中？

Question

我想要一个没有 Action Mailbox 或 Action Text 的新 Rails 6 应用程序，所以我创建了一个

rails new myapp --skip-action-mailbox --skip-action-text

然后我将它们删除application.rb

但当我运行时，bundle exec derailed bundle:mem它显示它们仍然存在：

rails/all: 36.2539 MiB
    action_mailbox/engine: 13.5313 MiB

如何删除它们以节省内存？

Answer 1

我有同样的问题，即使我application.rb看起来像这样：

%w(
  action_controller/railtie
  action_view/railtie
  active_job/railtie
  sprockets/railtie
).each do |railtie|
  begin
    require railtie
  rescue LoadError
  end
end

bundle exec derailed bundle:mem仍然显示这个：

      action_mailbox: 41.4688 MiB
