Linux 为什么添加导出DJANGO_设置_模块='；myproject.settings'；让bashrc不再工作？

我有一个在linux机器（Debian）上运行的Django应用程序。在过去的一段时间里，该应用程序运行得非常完美。最近，在芹菜任务开始挂起并且清除任务没有达到预期效果后，我需要重新启动机器。当我现在尝试开始使用芹菜时

sudo celery -A myapp.tasks worker -Ofair 

我收到了以下回溯

有没有办法让它再次工作？

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

---

（与您的问题无关，但您也不应该将bashrc编辑为sudo。）

如果有人想知道，因为我不得不想一想，sudo nano~/.bashrc中的~在调用sudo之前已展开，因此~仍然指原始用户，而不是根用户。Daniel-谢谢您，你完全正确！在sudo上运行相同的命令时没有遇到错误。你不知道我在这里发布之前花了多少时间来实现这个功能：万一有人想知道，因为我不得不想一想，

sudo nano~/.bashrc

中的~，你完全正确！在sudo上运行相同的命令时没有遇到错误。你不知道我在这里发布之前花了多少时间试图让它工作：s

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