在使用yum命令的时候提示
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:
2.7.6 (default, Sep 21 2017, 11:22:35)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
解决办法：
原因：yum和Python是依赖关系，yum是python的模块，所以采用以下解决方案：
命令whereis python
修改yum的配置
修改文件： vim /usr/bin/yum
修改头#!/usr/bin/python => #!/usr/bin/python2.6
再次运行，成功！！！
