如何在heroku上设置django-compressor,离线压缩到S3

我按照在SO和不同博客中找到的每个QA建议,在我的开发机器上一切正常,在heroku上没有任何作用.

这是我的设置:

DEFAULT_FILE_STORAGE = 'arena.utils.MediaRootS3BotoStorage' # media files
# storage

AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY')
AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME')
AWS_PRELOAD_METADATA = True # necessary to fix manage.py collectstatic command to only upload changed files instead of all files

S3_URL = 'https://%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME
MEDIA_URL = S3_URL + '/media/'

STATIC_URL = S3_URL + '/static/'

ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'


COMPRESS_URL = STATIC_URL
COMPRESS_OFFLINE = True
COMPRESS_STORAGE = 'utils.CachedS3BotoStorage'
STATICFILES_STORAGE = COMPRESS_STORAGE

当我运行collectstatic/compress时,一切正常,我看到文件被收集到S3并放入适当的位置.我看到了清单文件.

加载任何带有压缩标签的页面,显示错误再次OfflineGenerationError: You have offline compression enabled but key "d2a53169c44dec41ce3ee7da19b2b9d4" is missing from offline manifest.运行python manage.py compress不会解决任何问题.当我检查清单文件时,它确实找不到的密钥.

这里出了什么问题？
