使用： django-redis 4.10.0 python 3.6

Answer 1

django_redis试图从six导入django.utils

文件“ /home/yangcoco/.virtualenvs/Django_czbk/lib/python3.6/site-packages/django_redis/util.py”，第8行，从django.utils导入六个

但是，six已从django中删除。检查Django 3.0 release notes here

如果需要使用此特定版本的django_redis，请切换到最新的django_redis或Django 2.2

Answer 2

您可以尝试安装django-redis的最新版本来修复issue。

这将使您能够使用features that can change how you'll develop your app.随附的Django 3

要这样做，只需直接从GitHub安装该软件包，如果您像我一样使用Pipenv，只需发出以下命令：

pipenv install git+https://github.com/niwinz/django-redis.git@master#egg=django-redis

如果您仍然想使用Django 2.X，只需将Pipfile中的Django条目编辑为：

django = "==2.*"

或发出以下命令：

pipenv install "django==2.*"

django.core.cache.backends.base.InvalidCacheBackendError：找不到后端django_redis.cache.RedisCache'：无法导入名称“六个”
