Error installing devstack after pulling latest code

[Deepti Ramakrishna]

Hi all,

Ever since I did the latest git pull today, I am running into issues installing devstack.
./stack.sh fails with the below error. (please see the link below for full log.)

I am running on Ubuntu 14.04 LTS.

This issue happens, if we are trying to bring up devstack on a host, where there was a prior installation.
I see a related bug/discussion at [1], which might be helpful to track to get the right resolution to the issue.

Also, I worked-around the issue, by doing 'export PIP_UPGRADE=True' before running stack.sh, as suggested by[2]

HTH,
