# yum There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please 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: 2.6.6 (r266:84292, Aug 18 2016, 15:13:37) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
只能重装yum了
找台正常的机器
mkdir yum_rpms && cd yum_rpms
repoquery -R --resolve --recursive yum-3.2.29|xargs -I{} yumdownloader {} --destdir=.
# 卸载旧yum包
rpm -e --nodeps yum-3.2.29-81.el6.centos.noarch yum-plugin-fastestmirror-1.1.30-40.el6.noarch yum-metadata-parser-1.1.2-16.el6.x86_64

21870 2019-12-19_10:56:49 yum info并不是rpm -ivh * 就能解决的, 有依赖关系,缺哪个装哪个
