yum执行报错No module named yummain处理

Posted 2020-10-21

今天上服务器上执行yum install   htop出现 import yummain导入报错No module named yummain，于是百度查找问题处理方案，但是网上数说 执行yum clean all 即可  但是这个yum都不能执行了  clean 肯定也不行

1：解决方式

1获取yummain的安装的py文件

[[email protected] ~]# wget  http://yum.baseurl.org/download/3.4/yum-3.4.0.tar.gz

[[email protected] ~]# tar xf yum-3.4.0.tar.gz

[[email protected] ~]# cd yum-3.4.0

[[email protected] yum-3.4.0]# ls
AUTHORS      cli.pyc  INSTALL     po         test       yumcommands.py
bin          COPYING  Makefile    README     TODO       yumcommands.pyc
callback.py  docs     output.py   rpmUtils   utils.py   yummain.py
ChangeLog    etc      output.pyc  shell.py   utils.pyc  yum.spec
cli.py       FAQ      PLUGINS     shell.pyc  yum        yum-updatesd.py
[[email protected] yum-3.4.0]# ./yummain.py  install yum

base                                                         | 3.7 kB     00:00   

base/primary_db                                              | 4.5 MB     00:07   

extras                                                       | 3.5 kB     00:00   

extras/primary_db                                            |  23 kB     00:03

出现以上提示就证明yum已经安装成功了。

2：执行yum命令即可

[[email protected] yum-3.4.0]# yum update

3:你的yum现在可以使用了

[[email protected] yum-3.4.0]# yum install -y htop
