我无法运行服务器Django 2.0

Question

你好，我在尝试从Django 2.0旧项目运行服务器时遇到问题。你知道吗

这是错误：

      File "/usr/lib/python3.7/site-packages/django/urls/conf.py", line 39, in include
    'Specifying a namespace in include() without providing an app_name 
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.'

这是我的网址.py你知道吗

from django.conf.urls import url, include
from django.contrib import admin
from apps.sysgrub.views import LoginUser, LogoutUser

app_name = 'apps'

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^alumno/', include ('apps.alumno.urls', namespace="alumno")),
    url(r'^grupo/', include ('apps.grupo.urls', namespace="grupo")),
    url(r'^maestro/', include ('apps.maestro.urls', namespace="maestro")),
    url(r'^rol/', include ('apps.rol.urls', namespace="rol")),
    url(r'^sysgrub/', include ('apps.sysgrub.urls', namespace="sysgrub")),
    url(r'^$', LoginUser),
    url(r'^logout/$', LogoutUser),
]

和我的应用程序的网址

urlpatterns = [
url(r'^index$', index),
url(r'^horarios$', horarios),
url(r'^listar$', Alumno_grupoList.as_view(), name='alumno_listar'),
url(r'^agregar$', AlumnoCreate.as_view(), name='add_student'),

]

非常感谢你的帮助和问候。你知道吗

错误描述了解决方案。请从中删除应用程序名称网址.py如下所示

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^alumno/', include ('alumno.urls', namespace="alumno")),
url(r'^grupo/', include ('grupo.urls', namespace="grupo")),
]
