Question

我不断收到ImproperlyConfigured异常，并且无法从日志中找到任何线索。我从日志中发现的只有以下几行：

Traceback (most recent call last):
  File "/Users/marshall/PycharmProjects/chitchat-config/manage.py", line 25, in <module>
    django.setup()
  File "/Users/marshall/Library/Python/3.7/lib/python/site-packages/django/__init__.py", line 19, in setup
    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
  File "/Users/marshall/Library/Python/3.7/lib/python/site-packages/django/conf/__init__.py", line 79, in __getattr__
    self._setup(name)
  File "/Users/marshall/Library/Python/3.7/lib/python/site-packages/django/conf/__init__.py", line 64, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

这是设置结构

def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'app.dev_mac')

    log.info('Starting the application..')

    try:
        from django.core.management import execute_from_command_line

    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    import django
    django.setup()
    main()

到目前为止，我所知道的是，一开始应用程序将选择环境，此代码中为dev_mac。然后，应用程序将读取dev_mac.py文件，该文件将导入base.py。

据我所知，当无法解析设置但由于日志未充分说明代码而无法获得任何线索时，就会发生此异常。

有人能找出并告诉我为什么会发生吗？

Django-配置不正确
