Comment 2 for bug 850644

Hi Brad,

Nice work on the new structure for the plugins, but I think you missed something.
Since you commit, I can't install quantum with `python setup.py install --venv`

Exception: Command "pip install /root/quantum_default/common -E /root/quantum_default/.quantum-venv" failed.
Exception:
