from posts.views import index, blog, post

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', index),
    path('blog/', blog),
    path('post/', post),
]

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL,
                          document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL,
                          document_root=settings.MEDIA_ROOT)

ModuleNotFoundError: No module named 'posts'

Answer 1

在 INSTALLED_APPS 中，您应该像这样声明您的 posts:'posts.apps.PostsConfig' 要了解原因，请查看文件来自项目文件夹的 apps.py ；它应该看起来像这样:

from django.apps import AppConfig


class PostsConfig(AppConfig):
    name = 'posts'
