python版本包冲突

yum是用python开发的程序包安装管理器

由于主机Python版本升级，导致yum引用错乱，需要指定python具体版本号

python2.x和python3.x 是两个分裂的版本

通过python -V 可以查看python版本

root@172.16.24.220[/root]#python -V
Python 3.6.8

验证了下3.6.8版本指定会异常

查看旧版本python路径和版本号

root@172.16.24.220[/root]#whereis python
python: /usr/bin/python /usr/bin/python2.7 /usr/lib/python2.7 /usr/lib64/python2.7 /etc/python /usr/include/python2.7 /usr/share/man/man1/python.1.gz

修改/usr/bin/yum和/usr/libexec/urlgrabber-ext-down 文件
将#! /usr/bin/python 修改为#! /usr/bin/python2.7

验证
