I'm trying to use Django Compressor, which seems pretty straight-forward, but for some reason I keep getting an error, specifically:
When using Django Compressor together with staticfiles, please add 'compressor.finders.CompressorFinder' to the STATICFILES_FINDERS setting
My settings.py file includes the following:
DEBUG = True
INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    ...
    'compressor',
)
STATIC_URL = '/static/'
STATICFILES_FINDER = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'compressor.finders.CompressorFinder'
]
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, '_static'),
]
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
COMPRESS_ENABLED = True
I'm not sure if this is a compatibility issue with Django 1.10 (Django Compressor changelog states it is compatible with 1.10), or if Django Compressor simply is broken, since I've clearly added 'compressor.finders.CompressorFinder' to the STATICFILES_FINDERS setting. I've also tried with DEBUG=False.
Any help is appreciated.
                        
You just miss letter S in end of the SETTINGS VARIABLES. Just change
STATICFILES_FINDER -> STATICFILES_FINDERS
