Gunicorn导入错误：无法从docker中的“eventlet.wsgi”导入名称“ALREADY_HANDLED”
我有一个在 docker 中使用 gunicorn（eventlet worker）运行烧瓶的工作代码。它也在生产中工作，但在我的机器上，它开始这样做。我在谷歌上找不到关于这件事的任何信息。可能是什么问题？
Error: class uri 'eventlet' invalid or not found:

安装旧版本的 eventlet 解决了这个问题： pip install eventlet==0.30.2
- Just to note: there is a websocket DOS vulnerability in this version. `GHSA-9p9m-jm8w-94p2` the reason for the breaking change

最近好像有变化 eventlet
有关示例补丁和潜在发布版本，请参阅此 PR：https : //github.com/benoitc/gunicorn/pull/2581
Eventlet 0.30.3+ 删除了 wsgi.ALREADY_HANDLED 破坏公共 API，只是增加了补丁版本。对不起。
ALREADY_HANDLED 的问题：eventlet/eventlet#543 WSGI_LOCAL 的解决方案：eventlet/eventlet#544
如果使用 websockets，建议使用 eventlet>=0.31.0，因为旧版本容易受到 DoS 攻击。GHSA-9p9m-jm8w-94p2
CI 在 pylint 检查中失败，我没有接触过。
