yum 安装损坏

我尝试使用 yum update 更新我的服务器上的 CentOS，但出现以下错误：

Traceback (most recent call last):
  File "/usr/bin/yum", line 4, in <module>
    import yum
  File "/usr/lib/python2.7/site-packages/yum/__init__.py", line 59, in <module>
    import config
  File "/usr/lib/python2.7/site-packages/yum/config.py", line 30, in <module>
    from parser import ConfigPreProcessor, varReplace
  File "/usr/lib/python2.7/site-packages/yum/parser.py", line 4, in <module>
    import urlgrabber
  File "/usr/lib/python2.7/site-packages/urlgrabber/__init__.py", line 55, in <module>
    from grabber import urlgrab, urlopen, urlread
  File "/usr/lib/python2.7/site-packages/urlgrabber/grabber.py", line 1616
    errstr = str(e.args[1]) or pyerr2str.get(errcode, '<Unknown>')

我只能猜测我的 Python 存在一些严重问题。我该如何修复它？

PS 我对基于 Debian 的系统有经验，但对基于 rpm 的系统没有经验。这是我的第一个基于 rpm 的服务器，所以请多多包涵。

请尝试以下操作来清理 yum 缓存和元数据。

yum clean metadata && yum clean all

重建 RPM 数据库。

rm -f /var/lib/rpm/__db*
rpm -vv --rebuilddb

yum repolist如果你仍然有问题，请在此处输入输出
