Celery Elastic Beanstalk ImportError: cannot import name Celery

Question

我正在尝试通过 Django 让 celery 在 Elastic Beanstalk 上工作，但运气不佳。

我可以在我的本地机器上使用 celery，但是每当我部署到 Elastic Beanstalk 时，它都不喜欢这行：from celery import Celery。

我查看了其他一些关于此的问题，他们说将我的 celery.py python 文件的名称更改为 celeryapp.py 之类的名称，但这不会改变结果。

完整的错误信息是这样的：

  File "manage.py", line 10, in <module>
  execute_from_command_line(sys.argv)
  File "/opt/python/run/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line
  utility.execute()
  File "/opt/python/run/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 303, in execute
  settings.INSTALLED_APPS

  from .celery import app as celery_app
  File "/opt/python/bundle/3/app/MY_PROJECT/celery.py", line 5, in <module>
  from celery import Celery
  File "/opt/python/current/app/MY_PROJECT/celery.py", line 5, in <module>
  from celery import Celery
  ImportError: cannot import name Celery
   (ElasticBeanstalk::ExternalInvocationError)

有人知道为什么 celery 不能导入 Celery 吗？在我的 requirements.txt 中，我有 celery==3.1.18，所以我假设该库已安装。

Answer 1

requirements.txt 中也需要 django-celery。

更新： 我们也在部署后重新启动 celery 服务。

commands:
    90_create_post_dir:
        command: "mkdir /opt/elasticbeanstalk/hooks/appdeploy/post"
        ignoreErrors: true

files:
    "/opt/elasticbeanstalk/hooks/appdeploy/post/99_restart_delayed_job.sh":
        mode: "000755"
        owner: root
        group: users
        content: |
            #!/usr/bin/env bash
            service celeryd restart

您显然需要设置 celery 以作为守护程序运行，以及整个过程。
