I have installed devstack on my Ubuntu 14.04 LTS, 64-bit, using the newest build from the official repo.
Whenever I run openstack --help in the terminal, usage, description and optional arguments all display normally, but all except 2~4 commands display like this:
Could not load EntryPoint.parse('server_show = openstackclient.compute.v2.server:ShowServer')
Could not load EntryPoint.parse('server_ssh = openstackclient.compute.v2.server:SshServer')
Could not load EntryPoint.parse('server_suspend = openstackclient.compute.v2.server:SuspendServer')
Running openstack --debug --help shows that the root of these problems seems to be version conflict of python (all of the commands share the last two lines):
Could not load EntryPoint.parse('backup_list = openstackclient.volume.v1.backup:ListBackup')
Traceback (most recent call last):

I double checked, and I have both python 2.7.6 and 3.4.3 installed. As per this answer to an unrelated question, I set up alias python=python2, but this didn't seem to change anything. Setting back alias python=python3 didn't help either. (Alias is working, since python --version displays the correct version number.)
I've found another person with the exact same problem, but nobody commented on their post.
I suspect this error might be a symptom of a configuration/installation problem that causes other basic commands to display anomalous behaviour. Is there any way I can fix it?
https://github.com/openstack/requirements/commit/840d85eb5301cc63225f1fd7fbdb4f9ca2cc8489 has update python-neutronclient to ===3.1.0, which happens at sep 23, which means both master and stable/liberty have such change, stable/kilo has pined it to 2.6.0. I don't know what version are you using, and what newest are you mean.
