为什么它没有设置 DEBUG = True？

Question

我正在一个带有 venv 的 Django 项目中工作。我的问题是下一个问题：我在下面的代码中配置了 DEBUG = TRUE，但似乎在 django 启动时未加载设置并启动此错误：You must set settings.ALLOWED_HOSTS if DEBUG is False.

我认为DEBUG在虚拟环境中发生了变化，因为我调试了我的代码，并且在启动服务器之前发现DEBUG为false

Answer 1

嗯，我发现了问题：

我忘记在manage.py中的配置位置重命名名称，所以venv无法找到配置，然后他相应地设置了默认配置（DEBUG = False）
