python-2.7 - 获取导入错误 : cannot import name OrderedDict

Question

我收到错误

ImportError: cannot import name OrderedDict

在我的 ubuntu 14.04 机器上本地安装服务器时。我尝试手动安装ordereddict，也尝试升级kombu，但它仍然给出错误。完整的回溯添加如下-

rishav@Swastik:~/open-event-orga-server$ sudo python create_db.py
Traceback (most recent call last): File "create_db.py", line 5, in
from app import current_app
File "/home/rishav/open-event-orga-server/app/init.py", line 23, in
from celery import Celery
File "/usr/local/lib/python2.7/dist-packages/celery/init.py", line 133, in
from celery import five # noqa File "/usr/local/lib/python2.7/dist-packages/celery/five.py", line 153, in
from kombu.utils.compat import OrderedDict # noqa
ImportError: cannot import name OrderedDict

这解决了我的问题:

将昆布降级到 2.5.16。

重新安装 django-celery
