Question

我在Linux机器上运行了一个Django应用程序（Debian）。在过去的一段时间里，应用程序运行良好。最近我需要在芹菜任务开始挂起后重启机器并清除任务没有达到预期的效果。当我现在尝试使用

开始芹菜

sudo celery -A myapp.tasks worker -Ofair

我看到了以下追溯

我已将导出添加到bashrc（最后），以解决过去的问题，但现在我仍然遇到了同样的错误：

sudo nano ~/.bashrc
export DJANGO_SETTINGS_MODULE='myproject.settings'

有没有办法让这个再次起作用？

您正在使用sudo启动芹菜，这意味着您以root用户身份运行，而不是您为其设置环境变量的用户。不要那样做 - 用sudo运行守护进程绝对没有理由。

（与您的问题无关，但您也不应该将bashrc编辑为sudo。）

为什么要添加导出DJANGO_SETTINGS_MODULE =＆＃39; myproject.settings＆＃39;到bashrc不再有效？
