刘老师，您好。您的资料非常详细，刚刚学完python基础语法和pycharm。
可能是配置环境有问题吧，我按照您的教成做。在项目中的views中，加入如下代码：
from django.contrib import admin
from django.urls import include
from django.urls import path
urlpatterns = [
path('polls/', include('polls.urls')),
path('admin/', admin.site.urls),
]
编译时出错了，返回很多错误，最后如下：
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
请问这是什么原因造成的呢？
