I am running into problems with Devstack installation. I git cloned a fresh Devstack on my machine. Ran ./stack.sh once, and hit the following problem.

Further, I did ./unstack.sh to and ./clean.sh to clean everything. The same error resulted.
So, I tried two more options of using virtual environments using pyvenv and virtualenv. Both of them gave the same error that is shown below.

You appear to be running under a python virtualenv.
DevStack does not support this, as we may break the
virtualenv you are currently in by modifying
external system-level components the virtualenv relies on.
We recommend you use a separate virtual-machine if
you are worried about DevStack taking over your system.
Any pointers on how to overcome will be greatly appreciated.
Thanks in advance.
I suspect the devstack script is failing on this line of code. Which means you want to go to the else branch of code. To do this you need to add enable_service n-cell to your existing local.conf settings.
[[local|localrc]]
#NOVA
enable_service n-cell
I learned to enable the service by looking at this commit
The commit message states:
"When cellsv1 is used (n-cell is enabled) skip calling cells_v2 simple_cell_setup, which will never have hosts at the top level and which will always fail."
Now I'm stuck trying to resolve version conflicts with Cliff and hacking python packages. I hope this helps.
