SaltStack安裝時python版本沖突導致安裝失敗

saltstack 自動化運維 linux 集群 python yum -y install salt-master 安裝時，出現以下報錯：
file /usr/lib64/python2.6/zipfile.pyc from install of python-libs-2.6.6-66.el6_8.x86_64 conflicts with file from package python-2.6.6-36.el6.x86_64 file /usr/lib64/python2.6/zipfile.pyo from install of python-libs-2.6.6-66.el6_8.x86_64 conflicts with file from package python-2.6.6-36.el6.x86_64
從報錯信息中可以發現conflicts，這是沖突的意思，即python-libs-2.6.6-66.el6_8.x86_64與python-2.6.6-36.el6.x86_64發生沖突；
查詢發現系統已經安裝了2.6.6-26版本
[root@m01 ~]# rpm -q python-libs
python-libs-2.6.6-36.el6.x86_64
[root@m01 ~]# rpm -q python
python-2.6.6-36.el6.x86_64而yum安裝salt-master的版本是2015.5.10-2.el6 ，需要python-libs-2.6.6-66.el6.x86_64
python-libs-2.6.6-66.el6_8.x86_6
python-2.6.6-36.el6.x86_64嘗試卸載發生沖突的包然後安裝需要的版本，可以發現卸載不了，這個包被其它包依賴，受保護，不能卸載
yum -y remove python-2.6.6-36.el6.x86_64
Error: Trying to remove "yum", which is protected You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest
換個思維，那我是否可以升級
yum -y update python-2.6.6-36.el6.x86_64
[root@m01 ~]# rpm -qa python-libs
python-libs-2.6.6-66.el6_8.x86_64
[root@m01 ~]# rpm -qa python
python-2.6.6-66.el6_8.x86_64升級後果然可以安裝salt-master了
