quantum essex milestone-3 install procedure (fail)

Asked by Alejandro Comisario

Hi, we are trying to install quantum server and python quantum client.

We downloaded : python-quantumclient-2012.1~e3.tar.gz and quantum-2012.1~e3.tar.gz.

Installed both , and after installation, when we executed quantum-server we received :

root@ism16vms:~# quantum-server
Traceback (most recent call last):
  File "/usr/local/bin/quantum-server", line 9, in <module>
    load_entry_point('quantum==2012.1', 'console_scripts', 'quantum-server')()
  File "/usr/local/lib/python2.6/dist-packages/pkg_resources.py", line 337, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/local/lib/python2.6/dist-packages/pkg_resources.py", line 2279, in load_entry_point
    return ep.load()
  File "/usr/local/lib/python2.6/dist-packages/pkg_resources.py", line 1989, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
  File "/usr/local/lib/python2.6/dist-packages/quantum-2012.1-py2.6.egg/quantum/server/__init__.py", line 36, in <module>
    from quantum import service
  File "/usr/local/lib/python2.6/dist-packages/quantum-2012.1-py2.6.egg/quantum/service.py", line 19, in <module>
    from quantum.common import config
ImportError: No module named common

And when we executed quantum, we had :

root@ism16vms:~# quantum
Traceback (most recent call last):
  File "/usr/local/bin/quantum", line 9, in <module>
    load_entry_point('python-quantumclient==2012.1', 'console_scripts', 'quantum')()
  File "/usr/local/lib/python2.6/dist-packages/pkg_resources.py", line 337, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/local/lib/python2.6/dist-packages/pkg_resources.py", line 2279, in load_entry_point
    return ep.load()
  File "/usr/local/lib/python2.6/dist-packages/pkg_resources.py", line 1989, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
ImportError: No module named client.cli

So, after linking "/usr/local/lib/python2.6/dist-packages/python_quantumclient-2012.1-py2.6.egg/quantum/common" and "/usr/local/lib/python2.6/dist-packages/python_quantumclient-2012.1-py2.6.egg/quantum/client" to "/usr/local/lib/python2.6/dist-packages/quantum-2012.1-py2.6.egg/quantum" quantum-server worked.

So, did we install wrong both python-quantumclient and quantum that we needed to make this links to make it work ?

Hi Alejandro,

We actually discovered this issue on Friday, right after the we posted E-3. It was introduced by the last minute splitting of Quantum into separate client & server repos. You did not do anything wrong, and we're in the process of updating the documents to describe a work around.

One simple work around is to copy the __init__.py file from quantum-<version>/quantum/__init__.py (in the server tarball) to python-quantumclient-<version>/quantum/__init__.py, before you run setup.py in the python-quantumclient directory.

You can also probably copy that file into the appropriate location post install, but I haven't tested that exactly. Linking the directories should not be necessary, and we are fixing this issue in E-4. Sorry for the inconvenience on this one! Docs should be updated for this later today.

Following the instructions in the essex-3 admin guide I still had the issue describe by Alejandro. Linking the common and client directories from python client to quantum solved the issue.

Here is the python path:
