nova-api did not start "No module named keystonemiddleware.auth_token"
I am trying to install openstack stable/icehouse on ubutnu 12.04 through devstack. While running stack.sh I am facing the following error:
[ERROR] /home/stack/devstack/lib/nova:703 nova-api did not start
The n-api screen in rejoin-stack.sh says:
ImportError: No module named keystonemiddleware.auth_token
Could someone let me know how to proceed.
