No module named openstack.common

[Jtwebman]

I install the latest python-novaclient using pip and when I run the nova list I get a ERROR (ImportError): No module named openstack.common.

I am on the latest Mac OS.

Here is the full output with debug.

Ok after researching this and digging through source code it looks like it is actually an issue with the Rackspace extensions. There are pull requests out to already fix this here:

https://github.com/rackerlabs/rax_default_network_flags_python_novaclient_ext/pull/13
https://github.com/rackerlabs/os_virtual_interfacesv2_ext/pull/4
https://github.com/rackerlabs/os_networksv2_python_novaclient_ext/pull/13
https://github.com/rackerlabs/ip_associations_python_novaclient_ext/pull/2

I just made the changes to the files manually to get it working on my local which was novaclient.openstack.common.utils class is now just novaclient.utils if you are getting the same error.

Thanks Jtwebman for updating this and linking the pull requests for the rackspace extension fixes

What's the best way to go about updating this on a mac?

I get the same error, and I'm dead in the water.

2 days of fighting with it, I get it working a minute after I ask for help...

Here's what worked for me on my Mac

sudo su -
pip freeze | grep -v "^-e" | xargs pip uninstall -y
exit
pip install python-openstackclient

Good now

For me, this was due to os-networksv2-python-novaclient-ext.

sudo pip uninstall os-networksv2-python-novaclient-ext

How I found out:

I was using the python-openstackclient, but it might show up the same using just novaclient.

openstack --debug server list

Which showed at the bottom of the output:

  File "/Library/Python/2.7/site-packages/os_networksv2_python_novaclient_ext.py", line 16, in <module>
    from novaclient.openstack.common import cliutils as utils
ImportError: No module named openstack.common

Sure enough:

$ pip freeze | grep ext
os-networksv2-python-novaclient-ext==0.25

So, again, I ran this to fix it:

sudo pip uninstall os-networksv2-python-novaclient-ext
