python - not - from django.urls import include, path
Django: de django.urls import reverse; ImportError: Ningún módulo llamado urls (1)
Estás en Django 1.9, deberías hacer:
from django.core.urlresolvers import reverse
La versión 1.10 es donde puedes hacer from django.urls import reverse
Esta pregunta ya tiene una respuesta aquí:
Estoy trabajando en el tutorial de DjangoProject con la aplicación de encuestas. Como dice el tutorial en la parte 4, estoy tratando de importar ''reverse'': from django.urls import reverse pero obteniendo el error:
de importación django.urls inversa ImportError: ningún módulo llamado urls
Cambié el ROOT_URLCONF a solo '' urls '', sin embargo, tampoco funcionó.
Cualquier ayuda se agradece, gracias.
