Comment 9 for bug 1187452

I am unable to run the neutron unit tests because of this problem as well. The command "tox -e py27" failed during the setup of python-quantumclient 2.2.2. The failure occurred when the python-quantumclient 2.2.2's setup tried to install pbr. I didn't keep the exact error message, but it said it that is unable to find a suitable pbr version that satisfies python-quantumclient's requirements. The version is "pbr>=0.5.10,<0.6".

One thing I noticed is that in the python-quantumclient's requirements.txt file, required version pbr is ">=0.5.16,<0.6". So it is not clear where the version 0.5.10 is derived.
