yum出现“No module named yum”错误解决方法

 

安装了一个Python2.7，隔天发现yum无法使用，报错信息如下,应该是系统是使用的默认的python2.4的版本

------------------------------------------------------------------------------------------------

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

------------------------------------------------------------------------------------------------

解决办法

修改yum文件

#vi /usr/bin/yum

将 #!/usr/bin/python 修改为 #!/usr/bin/python2.4
