ModuleNotFoundError: 没有使用 celery 和 rabbitmq 的名为 'django.config' 的模块

Posted 2023-02-23

【中文标题】ModuleNotFoundError: 没有使用 celery 和 rabbitmq 的名为 \'django.config\' 的模块

【英文标题】：ModuleNotFoundError: No module named 'django.config' using celery and rabbitmqModuleNotFoundError: 没有使用 celery 和 rabbitmq 的名为 'django.config' 的模块

【问题描述】：

运行以下命令后出现此错误：

C:\Users\callu\project_name>celery -A project_name worker -l info

我想知道这是否与我没有在虚拟环境中创建我的 django 项目但我找不到任何关于这个问题的事实有关。如果是因为它位于虚拟环境之外，我不确定如何在不重新启动项目的情况下解决它（在 PyCharm 中迁移到 venv 是否容易？）

我在这里运行我的 django 服务器和上面的 celery 命令：

C:\Users\callu\project_name>

我在另一个位置（不是 venv）运行启动我的 RabbitMQ 服务器，但不认为这是问题

ModuleNotFoundError: No module named 'django.config'

【问题讨论】：

django.config 来自哪里？ （如果你错过了，那不是最初的例外。）

啊，我没有意识到这不是第一个异常，遗憾的是，该异常不是很具有描述性，cached_property.py 文件中的字典出错？ django.cofig 在我的celery.py 文件中app.config_from_object('django.config:settings', namespace='CELERY')。至少我认为它是从那里来的。

也许你的意思是'django.conf:settings'？

是的！如此简单，不敢相信我一直错过，感谢您的帮助

你能用cached_property重现异常吗？ Scripts\celery.exe\__main__.py", line 7 是什么？

【参考方案1】：

听起来您在某个地方（在您的应用程序/celery.py，如果使用标准布局）有如下一行：

app.config_from_object('django.config:settings', namespace='CELERY')

app 是你的 Celery 应用对象。

但你需要的是：

app.config_from_object('django.conf:settings', namespace='CELERY')

注意：您的 django 配置模块是 django.conf 而不是 django.config。
