【问题描述】：

当我发出 runserver 命令时，会从 djcelery (Django Celery) 引发 ImportError。

% python manage.py runserver

    from celery.app import default_app
ImportError: No module named app

在 python 控制台中手动尝试导入 celery.app.default_app 时也会出现同样的问题：

>>> from celery.app import default_app
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named app

【问题讨论】：

我们可以假设您使用的 celery 版本足够新，可以拥有 celery.app？
哈！请以答案的形式重新发布您的问题，以便我将其标记为解决方案。从 github 安装最新的主干构建后，它可以工作了。

【解决方案1】：

celery.app 仅在 9 月 14 日添加。您需要运行从那时起发布的 celery 副本。
