python编程：从入门到实践18章映射URL出现TypeError.

在runserver中报错：
TypeError: view must be a callable or a list/tuple in the case of include().

#learning_log/urls.py

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('learning_logs.urls', namespace='learning_logs')),
]

#learning_logs/urls.py

from django.urls import path
from . import views

app_name = 'learning_logs'
urlpatterns = [
    #主页
    path('', views.index, name='index'),

]

有没有大佬帮忙看看哪里出问题了

没错，重新runserver即可。
