【 使用环境 】 测试环境
【 OB or 其他组件 】OBD
【 使用版本 】1.6.0
【操作系统】Anolis-8.6
【问题描述】使用OBD命令安装OceanBase集群的时候提示缺少pymysql模块，但是这个模块已经安装了，有知道是哪里的问题吗？报错截图以及相关信息在下方附件！
【复现路径】下载 all-in-one社区版4.0版本的tar包，安装OBD工具，然后执行OBD安装集群的命令，出现缺少pymysql模块的问题。https://www.oceanbase.com/docs/community-observer-cn-10000000000900491
【问题现象及影响】
无法成功安装集群，不可用。
