[Justin Pomeroy (jpomero)]

I'm also seeing this problem in my openstack distro build. I could be wrong but it seems to be this import statement from openstack_dashboard/static/dashboard/scss/horizon.scss:

@import "/bootstrap/scss/bootstrap";

I think the intent is to import the bootstrap.scss file but since there is also a folder called bootstrap in the same location it fails with the "IOError: [Errno 21] Is a directory" error. Maybe if the folder or file were just renamed?

[Julie Pichon (jpichon)]

I wonder if there may be a relation with bug 1342079 (hardcoded /static/ prefixes), since the environments where this is happening don't use the default dev values?

Patch at https://review.openstack.org/#/c/110755/

[Radomir Dopieralski (deshipu)]

What I would like to know is why this is working just fine for everyone else.

[Julie Pichon (jpichon)]

I'm not sure how many people have tested the patch outside of devstack yet? I compared library version numbers with Derek but couldn't see any meaningful difference, I'm not sure what is causing the issue.

[Gregory Haynes (greghaynes)]

I imagine you meant devtest (not devstack), which is where we have been testing it.

I am also surprised others are not running into this issue. It happens as a result of the django compress script, so I wonder if most people are not running this? Seems like there should also be a test added for running this...

[Matthias Runge (mrunge)]

I'm running this: as checkout from github, installing dependencies via rpm (not using virtualenv or pip at all).
I haven't seen that issue.

[Radomir Dopieralski (deshipu)]

I think I found the problem:
