This is a workaround for https://bugs.launchpad.net/horizon/+bug/1367590
|
|
It works by creating a path that django_scss will attempt to create
|
|
later if it doesn't exist. The django_pyscss code fails
|
|
intermittently because of concurrency issues. This code ignores the
|
|
exception and if it was anything other than the concurrency issue
|
|
django_pyscss will discover the problem later.
|
|
|

TODO (doug-fish): remove this workaround once fix for
|
|
https://github.com/fusionbox/django-pyscss/issues/23 is picked up.
