我在这里看过这个例子：
http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html
我的所有任务都在名为tasks.py的文件中 .
更新芹菜并从示例中添加文件django抛出以下错误，无论我尝试什么：
ImportError: cannot import name Celery
问题可能是由以下原因引起的吗？
app.autodiscover_tasks(settings.INSTALLED_APPS, related_name='tasks')
因为它遍历所有具有以下导入的tasks.py文件 .
from cloud.celery import app
cloud/celery.py ：
from __future__ import absolute_import
import os, sys
from celery import Celery
from celery.schedules import crontab
from django.conf import settings
BROKER_URL = 'redis://:PASSWORD@localhost'
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'cloud.settings')
app = Celery('cloud', broker=BROKER_URL)
app.config_from_object('django.conf:settings')
app.autodiscover_tasks(settings.INSTALLED_APPS, related_name='tasks')
if "test" in sys.argv:
app.conf.update(
CELERY_ALWAYS_EAGER=True,
)
print >> sys.stderr, 'CELERY_ALWAYS_EAGER = True'
CELERYBEAT_SCHEDULE = {
'test_rabbit_running': {
"task": "retail.tasks.test_rabbit_running",
"schedule": 3600, #every hour
},
[..]
app.conf.update(
CELERYBEAT_SCHEDULE=CELERYBEAT_SCHEDULE
)
retail/tasks.py ：
from cloud.celery import app
import logging
from celery.utils.log import get_task_logger
logger = get_task_logger('tasks')
logger.setLevel(logging.DEBUG)
@app.task
def test_rabbit_running():
import datetime
utcnow = datetime.datetime.now()
logger.info('CELERY RUNNING')
当我尝试访问无效的URL（如/ foobar）时，会发生错误 .

我得到了同样的错误 . 事实证明我的Celery版本存在问题 . 我升级到3.1并且 celeryd 现在已弃用此版本（http://celery.readthedocs.org/en/latest/whatsnew-3.1.html） . 所以我不得不降级到3.0.19版本，这是之前用于该项目的稳定版本，到目前为止它运行良好 .
无论如何，如果你不想降级，3.1版本中的celeryd替换是 celery worker . 点击此处查看更多信息：http://celery.readthedocs.org/en/latest/userguide/workers.html .
希望这可以帮助！ :)
我得到了同样的错误 .
似乎
from __future__ import absolute_import不适用于Python 2.6.1，仍然没有引发错误 .升级到Python 2.7.5，它刚刚起作用 .
将以下行添加到cloud / celery.py：
给了我文件本身而不是库中的芹菜模块 . 将celery.py重命名为celeryapp.py并调整导入后，所有错误都消失了 .
注意：
这导致了启动 Worker 的变化：
对于那些运行celery == 3.1.2并且收到此错误的人：
应用此处提到的补丁：https://github.com/celery/celery/issues/1637
使用Django 1.7.5，Celery 3.1.17和Python 2.7.6，我发现我还是得到了这些
ImportError: cannot import name Celery. 但只有在PyCharm 4.0.4下运行测试时 .我发现 not 的解决方案依赖于
from __future__ import absolute_import，如First Steps with Django所述 . 相反，我将proj/proj/celery.py重命名为proj/proj/celery_tasks.py，然后将__init__.py的内容更改为匹配：from .celery_tasks import app as celery_app. 不再有多个名为celery.py的文件实例导致导入混乱似乎是一种更简单的方法 .你添加了这条线：
from __future__ import absolute_import到
cloud/celery.py模块的顶部？阅读此处示例的细分：http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html
为我工作（部署在服务器后的一些错误）：从项目中删除所有* .pyc文件并重新启动它 .
得到了同样的错误
我的芹菜设置文件名（celery.py）与'celery'包有冲突...
所以当做这个 - >从芹菜进口芹菜，它提出错误 - 不能导入名称芹菜
解决方案 - >只需将'celery.py'更改为'celery-settings.py'之类的其他内容
For someone who want to know what cause this error ：
我刚才遇到这个问题，然后我发现了问题--- sys.path .
也许你像我一样添加一些sys.path的路径，我在manage.py中添加以下代码，
所以，
from celery import Celery会首先在SRC_PATH和CONF_PATH搜索芹菜，这就是问题所在 .改成
它将首先搜索python的
lib和site-packages. 完美解决了 .请注意，较旧的Django项目将
manage.py脚本与项目目录放在同一目录中 . 也就是说，结构如下所示：而不是这个：
在这种情况下，您只需将
celery.app文件重命名为不同的文件，如上面接受的答案中建议的celeryapp.py.
