启动 django 服务器时出错

今天刚开始学习django，报错。

在 settings.py 文件中：

INSTALLED_APPS = [
    'webexample',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

在 urls.py 文件中：

from django.contrib import admin
from django.urls import include, path
urlpatterns = [
    path('admin/', admin.site.urls),
    path('webexample/', include('webexample.urls'))
]

webexample 应用程序已创建。

启动服务器时：

python manage.py runserver

给出错误消息：

该怎么办？

蟒蛇版本：3.6.3
