错误：包 'stomp.py' 需要不同的 Python：2.7.12 not in '>=3.6,<4.0'？

Question

我正在尝试ElastAlert在我的 ubuntu 16.04上安装，每当我运行时，我都会遇到pip install elastalert错误。我目前正在运行 python 2.7.12。任何帮助，将不胜感激。我是新手，所以不确定我做错了什么。错误信息如下：-

    DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. 
Please upgrade your Python as Python 2.7 is no longer maintained. 
pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

错误比较明显。您尝试安装的软件包仅支持 Python 3.6+。

您的选择是安装更新的 python（网上有很多指南）或升级到更新的 Ubuntu LTS 版本（16.04 即将结束生命周期）。
