Python 3.x 插件Stopmotion预览无法在Engure 2.0中启动

给出以下错误代码：

AttributeError: 'CameraManager' object has no attribute 'get_builder'

CameraManager对象的帮助（）：

class CameraManager(gi.repository.Gtk.ApplicationWindow, Progress)
 |  CameraManager(*args, **kwargs)
 |  
 |  :Constructors:
 |  
 |  ::
 |  
 |      CameraManager(**properties)
 |      new(app:Entangle.Application) -> Entangle.CameraManager
 |  
 |  Method resolution order:
 |      CameraManager
 |      gi.repository.Gtk.ApplicationWindow
 |      gi.overrides.Gtk.Window
 |      gi.repository.Gtk.Window
 |      gi.repository.Gtk.Bin
 |      gi.overrides.Gtk.Container
 |      gi.repository.Gtk.Container
 |      gi.overrides.Gtk.Widget
 |      gi.repository.Gtk.Widget
 |      gi.repository.GObject.InitiallyUnowned
 |      gi.overrides.GObject.Object
 |      gi.repository.GObject.Object
 |      gi._gi.GObject
 |      gi.repository.Atk.ImplementorIface
 |      gi.repository.Gtk.Buildable
 |      gi.repository.Gio.ActionGroup
 |      gi.overrides.Gio.ActionMap
 |      gi.repository.Gio.ActionMap
 |      Progress
 |      gobject.GInterface
 |      builtins.object
 | 

任何地方都没有“get_builder”方法。谁应该拥有这种方法

我没有找到gi.repository.tengle等的任何文档。我认为CameraManager是一个Gtk.Windows对象，一个Builder对象包含对所有已创建窗口的引用，“get_Builder”应该提供链接吗

谢谢你的建议
