django - 连接 django-rq : ImportError: cannot import name get_failed_queue 时出错

Question

从未使用过django-rq、redis。我想这个问题应该很容易解决，但我不知道如何解决。

当我启动服务器时，出现此错误 ImportError: cannot import name get_failed_queue

我正在使用 Python 2.7

发生这种情况是因为您使用的 django-rq==2.0 需要 rq>=1.0。 rq==1.0 中不再存在函数 get_failed_queue()，请阅读发行说明以了解如何更改代码以使其再次运行:https://github.com/rq/rq/releases/tag/v1.0

否则，你可以降级到 django-rq==1.3.1 和 rq==0.13
