【问题描述】：

我正在使用 linux (fedora) 机器，我想在 python3.3 中使用 celery。当我执行这些命令时：

celery -A tasks worker --loglevel=info
celery worker --help

我收到以下错误：

    [root@localhost gert]# celery -A tasks worker --loglevel=info
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

我已经安装了所需的包，所以我在 python3.3 中的站点包映射如下所示：

celery-3.1.0rc1-py3.3.egg
amqp-1.2.0-py3.3
anyjson-0.3.3-py3.3.egg
billiard-3.3.0.0rc1-py3.3.egg
distribute-0.6.28-py3.3.egg-info
easy_install.py
kombu-2.5.9-py3.3.egg
pip-1.2.1-py3.3.egg-info
pkg_resources.py
pycache（带下划线）
python_dateutil-2.0-py3.3.egg
pytz-2013b-py3.3.egg
设置工具
setuptools-0.6c11-py3.3.egg-info
site.py
six-1.3.0-py3.3.egg

有谁知道我错过了什么，或者我做错了什么？

【问题讨论】：

请包含错误的完整回溯。
我编辑了我的帖子，感谢您的反馈
你一定用的是开发版的 Celery，对吧？由于 3.1 尚未发布。您很可能遇到了仍然需要纠正的错误，您是否向Celery issue tracker 提出了问题？
我还没有，因为完全相同的安装确实可以在我的虚拟机上运行。我能够执行所有 celery 命令。当我在我的其他 Fedora 客户端（双启动）上重新安装所有内容时，它给了我这个错误。我确实从 github 下载了 celery，也许 some1 同时做了一个提交？
我说很很可能有人在此期间提交了；看着commit history Ask 挺忙的。

【解决方案1】：

正如 martijn 所说，答案很简单。有人在 github 上对 celery 项目进行了提交，我提取了我以前的版本，现在它可以工作了。这个错误在他们修复后应该不是什么大问题。
