devstack on fresh checkout fails

[Amrith Kumar]

On a fresh checkout, devstack fails as shown below

+ cd /opt/stack/requirements
+ python update.py /opt/stack/pbr
Traceback (most recent call last):
  File "update.py", line 35, in <module>
    from openstack_requirements import project
ImportError: No module named openstack_requirements

    33 import sys
    34
    35 from openstack_requirements import project
    36 from openstack_requirements import requirement
    37

UPDATE: This comment (the sentence below) which was in the original bug report is a red-herring.

This is new code that appears to be related to https://github.com/openstack/requirements/commit/b838ab1e43180d0b560bd24b211fe8947ac11f2b#diff-01ae00966b31668092462ac0be18b474

This should have been addressed in devstack weeks ago with https://review.openstack.org/193288 so I'm not sure why you're seeing this unless you're updating your copy of the requirements repo but not updating your copy of the devstack repo.

[Amrith Kumar (amrith)]

This is being seen on a machine with a fresh clone of everything.

i.e. brand new /opt/stack

Then get devstack (from master).

Retrying with commit d72b839b7f15a8065d2f7bcceff0a9299ea9c901

After 193288 you should see it calling "./.venv/bin/python update.py /opt/stack/pbr" rather than just "python update.py /opt/stack/pbr" there so I'm not sure why your log shows commands which haven't existed in devstack master for over two weeks.

Yes, thats running an old devstack.

THats 2 weeks old.

Based on IRC discussion, this report (using an old devstack) was done to debug the actual problem of old-pbr which is the bug I've marked thiss as a duplicate of.
