我正在尝试调试一个有问题的错误，该错误在我尝试启动我正在使用（以及其他）celery 和 rollbar 的 django 项目时发生。当我将日志级别更改为mail_adminsfrom ERRORto时，会出现问题WARNING。完整的追溯如下：

到目前为止，我已经完成了这个讨论，但没有一个建议的解决方案适用于我的案例。我开始怀疑日志记录是否存在问题，因为如果您查看回溯，会发现 rollbar reinit 警告的日志记录不是由环境 Python（位于env/目录中）而是由系统记录器处理的。
当我尝试运行 python 控制台时，我得到了这个：
(env)root@test:/var/www/papukurier_test# python

我的环境中没有loggin模块。
