今天用yum安装软件的时候出现如下错误:

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:

 

If you cannot solve this problem yourself, please go to the yum faq at:

yum 错误，搜索一番后知道是yum和python是依赖关系，yum是python的模块，所以采用以下解决方案：

[root@localhost ~]# python

Python 2.7 (r27:82500, Jul 26 2012, 00:43:02)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

系统python的当前版本  Python 2.7

 

[root@localhost ~]#whereis python python: /usr/bin/python /usr/bin/python2.4 /usr/lib/python2.4 /usr/include/python2.4 /usr/share/man/man1/python.1.gz

 

肯定是yum的版本与当前python的版本不一致造成的

所以修改yum的配置

修改文件： vim /usr/bin/yum

 

修改头 #!/usr/bin/python  => #!/usr/bin/python2.4

 

再次运行，成功！！！
