$ python --version
Python 3.8.3

如何解决这个问题？

Answer 1

简单搜索一下，它看起来像是从2017年的HBASE-1.4，而最新的稳定是2.2.5...发布说明暗示它可以与Python 3一起工作

考虑简单地使用较新的jar Apache归档链接来创建稳定的文件

在最新的Apache Phoenix代码中，至少psql.py确实支持Python 3 https://github.com/Apache/Phoenix/blob/master/bin/psql.py，因此您应该能够获得一个比现有版本更新的版本。

这可以在最近的提交中看到

• 在GitHub上按文件提交历史记录:https://github.com/apache/phoenix/commits/master/bin/psql.py
• 为Python3支持提交中的被修复

如果必须使用1.4.x，则可以使用Python 2运行psql.py。大多数操作系统将接受并行安装它们，尽管这可能会使某些依赖项管理变得混乱，而且这不是一个可维护的解决方案。
