No module named yum錯誤的解決辦法

今天用yum安裝軟件的時候出現以下錯誤:

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:

yum 錯誤，搜索一番後知道是yum和Python是依賴關係，yum是python的模塊，因此採用如下解決方案：

[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.

系統python的當前版本  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

 確定是yum的版本與當前python的版本不一致形成的

因此修改yum的配置

修改文件： vim /usr/bin/yum

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

 再次運行，成功！！！
