如何在windows上运行ccm (Cassandra Cluster Manager)命令

Question

我已经按照Datastax网站上的说明安装了ccm。

https://www.datastax.com/dev/blog/ccm-2-0-and-windows

和

https://pypi.org/project/ccm/3.1.4/

ccm已成功安装，但当我尝试运行它时，我得到错误，ccm不是一个可识别的命令。

c:\..\ccm-3.1.4.tar\dist\ccm-3.1.4>pip install ccm
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

我已经在PATH变量中添加了路径C:\Users\manu\Documents\manu\ccm-3.1.4.tar\dist\ccm-3.1.4。

如何在Windows上运行ccm？

Answer 1

我必须在PATH变量中设置PYTHON_HOME -> C:\<python_root>\

Answer 2

您可以考虑使用CCM的替代方法，它不需要python依赖项。比如在docker容器中运行cassandra，并使用docker-compose进行管理。

这里有一个例子：https://github.com/digitalis-io/ccc
