Out of curiosity, what version of Glance are you trying to run? Just
wanting to make sure this is not PY27/PY3 thing as I recall us having
issues with those dependencies at some point. So there might also be fixes
merged for those issues if it's an older release, but obviously recently we
have not supported PY27 anymore.
