Open Stack

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.
