Django collectstatic fails in CircleCI

python
circle.yml
#1

My build fails during the static file preparation. The exact same setup works fine on both my local and Heroku.

My stack:
Python 2.7.10
Django 1.9

Django settings for STATICFILES_STORAGE: 'pipeline.storage.PipelineCachedStorage'

My circle.yml file:

machine:
  timezone:
    Europe/Istanbul
  python:
    version:
      2.7.10
  environment:
    DATABASE_URL: postgres://ubuntu:@localhost:5432/dbname
    DEBUG: True
    ...
test:
  pre:
    - ./manage.py collectstatic --no-input

The error message and the traceback:

I’ve changed my app’s name to appname in the above log.

Edit:
If I change STATICFILES_STORAGE to 'django.contrib.staticfiles.storage.StaticFilesStorage' it works fine. But it doesn’t work with Pipeline.

Any idea how I can make it work with Pipeline too?
