Missing oslo.rootwrap package?

Hello,

I have a particular problem of not being able to creating new VM instance (Juno). The log says

Traceback (most recent call last):
  File "/usr/bin/nova-rootwrap", line 6, in <module>
    from oslo.rootwrap.cmd import main
ImportError: No module named rootwrap.cmd

Intuitively, i upgrade the oslo.rootwrap package by running upgrade and get:

pip install oslo.rootwrap --upgrade
Requirement already up-to-date: oslo.rootwrap in /usr/local/lib/python2.7/dist-packages
Cleaning up...

Nothing changed, the pkg seems already up-to-date.

Anybody knows how to deal with this? I've reinstalled all software packages for Nova for several times already, changed nothing. Could it be any other problems in Ubuntu (14.04) itself?

Thanks in advance!
