NoReverseMatch:'；应用程序名称'；不是注册的命名空间[django watson] Django:1.11 Python:3.5.x DB:SQLite

你好

我很确定我已经跟在后面了，但还是没有运气。运行

/manage.py buildwatson

时出错：

# ./manage.py buildwatson

Traceback (most recent call last):
  File "/home/zea/Riset/Python/env_vakansea/lib/python3.5/site-packages/django/urls/base.py", line 77, in reverse
    extra, resolver = resolver.namespace_dict[ns]
KeyError: 'app_trip'

During handling of the above exception, another exception occurred:

我卡住了。我在他们的github上发布了一个问题，但仍然没有回应。任何帮助都将不胜感激

多谢各位

# apps.py
