公司服務器重新安裝系統後，手動升級python2.7.5到2.7.15，安裝完python在更新系統python版本的過程中無意刪除了系統自帶的版本，導致後來在執行yum命令的時候出現了錯誤
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: 2.7.15 (default, May 21 2018, 11:43:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
考慮到原來系統使用的python版本為2.7.5，手動編譯安裝python2.7.5版本後還是出現該問題。
解決方法：
