一、yum命令不能使用
1报错
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:No module named yumPlease install a package which provides this module, or
verify that the module is installed correctly.It’s possible that the above module doesn’t match the
current version of Python, which is:2问题分析
大部分人出现这个错误的原因在于拿到服务器的第一时间发现python版本是2.x想升级到python3 导致yum损坏博主花了两个小时查阅资料最终总算解决问题。
3完全删除python及yum重新安装
1、删除python
#删除现有的python
[roottest ~]# rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps ##强制删除已安装程序及其关联
[roottest ~]# 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
[roottest ~]# whereis python ##验证删除返回无结果2、删除yum
#删除现有的yum
[roottest ~]# rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps
[roottest ~]# whereis yum |xargs rm -frv从中科163或者阿里云镜像下载相对应的包
centos版本可以根据自己的版本去找对应Packages 如果不知道自己的系统版本命令行输入这个cat /etc/redhat-release
中科 http://mirrors.ustc.edu.cn/centos/7/os/x86_64/Packages/163 http://mirrors.163.com/centos/7/os/x86_64/Packages/阿里 https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/
3、下载Python依赖rpm包
#下载Python安装包
python-libs-2.7.5-48.el7.x86_64.rpm #被python依赖
python-2.7.5-48.el7.x86_64.rpm
python-iniparse-0.4-9.el7.noarch.rpm #被yum依赖
python-pycurl-7.19.0-19.el7.x86_64.rpm #被python-urlgrabber依赖
python-urlgrabber-3.10-8.el7.noarch.rpm#被yum依赖
rpm-python-4.11.3-21.el7.x86_64.rpm#被yum依赖选用阿里地址下载访问阿地址搜索相关的包
https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/
#下载python包
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-libs-2.7.5-89.el7.x86_64.rpmwget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-2.7.5-89.el7.x86_64.rpmwget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpmwget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-pycurl-7.19.0-19.el7.x86_64.rpmwget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-10.el7.noarch.rpmwget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/rpm-python-4.11.3-45.el7.x86_64.rpm4、下载yum依赖rpm包
#yum安装包列表:
yum-3.4.3-150.el7.centos.noarch.rpm, 就是它依赖了上面的python库
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm
#下载yum包
mkdir -p yum-rpm/
cd yum-rpm/
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm5、强制安装python
#强制安装python--nodeps表示强制
rpm -Uvh python-libs-2.7.5-89.el7.x86_64.rpm --nodeps
rpm -Uvh python-2.7.5-89.el7.x86_64.rpm --nodeps

rpm -Uvh rpm-python-4.11.3-45.el7.x86_64.rpm --nodeps6、强制安装yum
#强制安装yum--nodeps表示强制
cd yum-rpm/
rpm -Uvh yum-3.4.3-168.el7.centos.noarch.rpm --nodeps
rpm -Uvh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm --nodeps
rpm -Uvh yum-plugin-fastestmirror-1.1.31-54.el7_8.narch.rpm --nodeps7、测试
yum install vim -y 【参考地址】
