Thanks for replying . Sorry I did not write explanation in this email. So I
sent another one. Basically, there are too many of this kind of conflicts, I
already manually fixed about 8, still more. If I fix them all this time, it
may still happen down the road if somebody update constrains or requrements. I
am just wondering why this thing was not happening before. I noticed that pip
was updated to version 9, my old good one was using pip version 8

Try to manually uninstall it first: sudo pip uninstall python-heatclient
Then launch devstack again. It will re-install the right version.
