我不熟悉Python，也许有人可以解释这是怎么回事？

也许有开源的替代品监测cassandra我应该看看？
非常感谢
导致错误的行from twisted.web.client import Agent, _parse 。 OpsCenter将分发的版本捆绑在一起以确保兼容性。 这听起来像是您正在使用的系统上安装了不兼容的扭曲版本。
编辑：亚马逊Linux AMI有一个已知的问题。 在/ user / share / opscenter / bin / opscenter中，在导出之前添加以下行：PYTHONPATH = …：PY_DISTRO =“./ lib / py-redhat / $ {PY_VER} / shared / $ {PY_ARCH}：./ LIB / PY-红帽/ $ {PY_VER} / 6 / $ {PY_ARCH}”
我们将不得不在OpsCenter中更好地处理这个问题，但是同时要取消第三方安装的扭曲，虽然不够高雅，但一定会让您启动并运行。
要确定是否安装了twisted： python -c "import twisted; print twisted"
