yum 无法使用的解决方法

yummain.user_main(sys.argv[1:], exit_code=True)

File "/usr/share/yum-cli/yummain.py", line 298, in user_main

errcode = main(args)

File "/usr/share/yum-cli/yummain.py", line 110, in main

base = cli.YumBaseCli()

File "/usr/share/yum-cli/cli.py", line 72, in __init__

output.YumOutput.__init__(self)

File "/usr/share/yum-cli/output.py", line 307, in __init__

self.reported_error_msgs = dict((k, False) for (k, v) in ERRORS_TO_KBASE_ARTICLES.iteritems())

NameError: global name 'ERRORS_TO_KBASE_ARTICLES' is not defined

查看yum命令第一行

[root@host ~]# cat /usr/bin/yum

#!/usr/bin/python

查看python版本2.6.6

[root@host ~]# python -V

Python 2.6.6

解决方法：

下载yum资源 rpm包地址：http://rpmfind.net/linux/rpm2html/search.php?query=yum

重新下载了一个yum的rpm包，重新升级安装即可；

# rpm -ivh yum-3.2.29-75.el6.centos.noarch.rpm
