Hi, I’m trying to set up an Openstack lab and need your assistance.

As a start, I tried installing Openstack Devstack on Ubuntu 14.04.4 LTS.

While executing the stack.sh, it got failed with the below error.

    Traceback (most recent call last):
  File "/opt/stack/requirements/.venv/bin/pip", line 7, in <module>
    from pip import main

Have you seen this error and do you know the fix?
