Question

我正在尝试按照文档开始使用celery，但遇到了难以调试示例代码的问题。我不知道我是否遇到了同样问题的两个方面，或两个独特的问题。我可以通过shell建立与SQS队列的连接，但不能与django连接。我不知道该行为与导入Celery与导入任务的问题的关系是什么。

此处的“使用入门”指南： http://celery.github.com/celery/getting-started/first-steps-with-celery.html#running-the-celery-worker-server

显示代码

from celery import Celery

如果我从python shell运行它，这段代码有效，但是，如果我在eclipse中的tasks.py中的django项目中执行此操作，我会收到错误Unresolved Import：Celery。

这里有一个单独的指南：http://celery.github.com/celery/django/first-steps-with-django.html代表django，而不是

from celery import task

然而，当我继续本教程并致电

时，哪个可以解决

add.delay(2, 2)

我收到连接失败，看起来好像它仍然试图仍然使用rabbitmq而不是SQS我有我的django项目设置使用（这有效，我可以从亚马逊的网络界面看到SQS队列，我如果我使用celery import Celery从shell执行所有操作，则可以建立连接。如果相关，则为堆栈跟踪：

在settings.py中，我使用我的SQS网址正确配置了BROKER_URL（并且在密码中没有正斜杠，这显然是过去的一个问题）。

所以

为什么“来自celery import Celery”的工作是从python shell开始的，而不是在django项目的eclipse中工作？
为什么按照django教程中的说明导致连接拒绝错误（amqplib引用是否意味着它尝试使用rabbitmq而不是SQS）？

您是否已将import djcelery; djcelery.setup_loader()添加到settings.py的顶部？

芹菜和django芹菜的API现在有所不同，因为django-celery落后了。 Celery 3.1将支持Django开箱即用，因此新API可以在任何地方使用。

关于有趣的日食事件。 Eclipse是否可以使用静态分析来查找模块中的符号？在这种情况下，将以下内容添加到celery / init .py文件中是否有帮助：
