【已解决/安装问题】安装任务报错：remove centos firewall pkg，因为ansible的Python版本问题

[yifliu]

Rainbond版本:offline.2019-09-03-5.1.7
操作系统:centos7.4
内核版本:
环境:(云服务商,虚拟机等)公司服务器
节点配置:单节点
安装类型:离线安装
如何复现:系统默认Python版本是2.7，安装时报过Python版本过低时升级到了3.6。现出现问题如下：
TASK [prepare : remove centos firewall pkg] *******************************************************

【已解决】离线安装包安装报错

系统版本：CentOS 7.4.1708 TASK [prepare : remove centos firewall pkg] ************************************ fatal: [42377e4d-396d-9e2a-00a3-456f272b79f2]: FAILED! => {"changed": false, "msg": "The Python 2 bindings for rpm are needed for this module.

发现社区里有人问过同样的问题，并解决了。

请问具体如何操作，要注释掉的任务流文件在什么位置？（/opt/rainbond/rainbond-ansibl这里面没找到），另外公司服务器关闭防火墙可能不太现实

TASK [prepare : install centos package] ***********************************************************

手动解决掉这个，又出来一个新任务报错，看来要从根源上解决了，请问要如何处理？

The Python 2 bindings for rpm are needed for this module. If you require Python 3 support use the dnf Ansible module instead.. The Python 2 yum module is needed for this module. If you require Python 3 support use the dnf Ansible module instead.

你可以卸载掉已经安装的python，然后执行一下看看
