Django即使发生在manage.py中的设置，“发生异常：请求配置设置不正确，但未配置...” 追加：

如何解决Django即使发生在manage.py中的设置，“发生异常：请求配置设置不正确，但未配置...” 追加：

对不起，我是Django的新手，如果我忘记了任何重要信息，请发表评论。

我已经在this VSCode tutorial之后设置了Django应用。简而言之，它教我在Venv中构建Django应用的docker映像。

当我开始使用VSCode运行时，发生错误，指出 Exception has occurred: ImproperlyConfigured Requested setting DEBUG,but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.。

但是，我的os.environ.setdefault('DJANGO_SETTINGS_MODULE','yiweis_blog.settings')和wsgi.py中都有manage.py。

同时，当我将外壳直接连接到容器并运行python manage.py runserver时，它将打印Django version 3.1.1,using settings 'yiweis_blog.settings'。

我也曾尝试将变量yiweis_blog.settings分配给DJANGO_SETTINGS_MODULE中的dockerfile并在终端中导出该变量，但是它们仍然没有起作用。

感谢您的帮助。谢谢！
