我正在使用django python 1.7和2.7。我有一个项目（'TEJUJAGUA'）里面有一个应用程序（'SIGAPPY'）。使用时应用程序正确执行。我的问题是我需要使用 pydoc 生成文档。
要执行此操作，请从位于文件manage.py所在目录的shell中运行命令：
pydoc -w ./
产生下一个输出：
wrote SIGAPPY.html
problem in SIGAPPY.FirstView - <class 'django.core.exceptions.AppRegistryNotReady'>: Models aren't loaded yet.
wrote SIGAPPY.admin.html
problem in SIGAPPY.forms - <class 'django.core.exceptions.AppRegistryNotReady'>: Models aren't loaded yet.
wrote SIGAPPY.models.html
wrote SIGAPPY.tests.html
problem in SIGAPPY.urls - <class 'django.core.exceptions.AppRegistryNotReady'>: Models aren't loaded yet.
wrote SIGAPPY.views.html
wrote TEJUJAGUA.html
wrote TEJUJAGUA.settings.html
problem in TEJUJAGUA.urls - <class 'django.core.exceptions.AppRegistryNotReady'>: Apps aren't loaded yet.
wrote TEJUJAGUA.wsgi.html
wrote manage.html
导致 pydoc 仅为某些文件生成html页面，但省略了其他文件，如FirstView.py，forms.py等。
有关此错误原因的任何想法？。
如果您需要任何其他代码段，我会发出警报。
