centos6.10 重新安装python2.6 和 yum (不可以直接安装yum yum 依赖于python2.6)

(升级或卸载Python导致 yum出错)

一: 升级python导致yum出错

1. cd  /usr/bin/yum

2.  #!/usr/bin/python 修改为    #!/usr/bin/python2.6

 

二 :完全重装python和yum(卸载系统的安装的python)

<1> 删除python包

1. whereis python  # 查看当前系统安装的python包

2. rpm -qa|grep python|xargs rpm -ev –allmatches –nodeps   ##强制删除系统安装程序python包及其相关

3. whereis python |xargs rm -frv   ##删除所有残余文件 ##xargs,允许你对输出执行其他某些命令

4. whereis python ##验证删除,返回无结果

<2> 删除现有yum

1.rpm -qa|grep yum|xargs rpm -ev –allmatches –nodeps

2.  whereis yum |xargs rm -frv

<3>下载相应的rpm包 (centos6版本) http://mirrors.ustc.edu.cn/centos/6/os/x86_64/Packages/
