Django + Celery: ImportError: No module named project.urls

When I start a worker using Django and Celery using this command (I execute the command within the d directory):

当我使用这个命令使用Django和Celery启动一个worker时(我在d目录中执行命令):

celery -A e.project.celery:app worker -l info

celery -A e.project.celery:app worker -l info

File "/Users/.../..../e/venv/lib/python2.7/site-packages/celery-4.2.0-py2.7.egg/celery/loaders/base.py", line 108, in import_default_modules
    raise response

ImportError: No module named project.urls

I am using Django 1.11 and Celery 4.2 with Python 2.7.

我在Python 2.7中使用Django 1.11和Celery 4.2。

Below is my project structure with the contents of some files that should be helpful for debugging.

下面是我的项目结构,其中包含一些有助于调试的文件的内容。

#   should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

As stated in the comments to the question, I see that you use e.project.celery and e.project.settings in your import statements, but the error says something about not finding project.urls (there is no e. at the start).

正如对问题的评论中所述,我看到你在import语句中使用了e.project.celery和e.project.settings,但错误说明了没有找到project.urls(开头没有e。) )。

How did you define the ROOT_URLCONF setting? Maybe that is causing the problem.

你是如何定义ROOT_URLCONF设置的?也许这就是导致问题的原因。
