python - Whitenoise、Mezzanine、Django -ImportError : cannot import name ManifestStaticFilesStorage

Question

我正在尝试在 heroku 上部署我的夹层项目。最后一个错误给了我一个最终的堆栈——ImportError: cannot import name ManifestStaticFilesStorage。这是我的核心项目结构:

wsgi.py:

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

简介:

web: gunicorn wsgi

最令人困惑的是 ImportError: cannot import name ManifestStaticFilesStorage 错误。

Answer 1

ManifestStaticFilesStorage 是在 Django 1.7 中引入的。您使用的是旧版本的 Django 吗？如果是这样，您应该升级到 supported version .

仍然可以使用 WhiteNoise 2.0.6使用旧版本的 Django，但我或 Django 团队都不支持。
