Question

需要帮助以了解我在做什么错：与Django框架有关，我正在尝试映射基本URL进行查看：这是应用程序的url.py：https://www.screencast.com/t/DODOUYBhYK 这是主项目的urls.py： https://www.screencast.com/t/NjjFQ9HQ 当我使用python manage.py makemigrations learninglogs（学习日志是应用程序）时，出现了此错误

(venv) C:\Users\Dell\PycharmProjects\Learning_Log>python manage.py makemigrations learninglogs
Traceback (most recent call last):
File "C:\Users\Dell\PycharmProjects\Learning_Log\venv\lib\site-packages\django\urls\resolvers.py", line 535, in url_patterns
iter(patterns)
TypeError: 'module' object is not iterable

During handling of the above exception, another exception occurred:

ppear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

当我从url_patterns删除下划线时，出现此错误：

    % (desc, ENVIRONMENT_VARIABLE))
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.

Process finished with exit code 1

找不到：django.core.exceptions.ImproperlyConfigured的解决方案：所包含的URLconf似乎没有任何模式
