error while executing ns-create :cannot import name get_errno

Asked by bhupesh

I am using Ocata release.

while executing ns-create, I get

MistralException: ImportError: cannot import name get_errno

Which seemes be occuring at line 18

 File "/usr/local/lib/python2.7/dist-packages/kombu/transport/base.py", line 18, in <module>

base.py, line 18 is:
18 from kombu.utils.compat import get_errno

I do not know python, can some one help me resolve this error

Thanks

Hi,

When I check my environment, I don't see kombu package. I am happy when it works ^^.

and, you are using Tacker?

I downloaded master code from github, build and installed. Seems to be working, hope no integration issue surface somewhere else.
