公司測試機環境不知道給我卸了什麼包，導致yum運行報錯狀況：
系統版本：Red Hat Enterprise Linux Server release 6.2 (Santiago)
內核版本：2.6.32-220.el6.x86_64
報錯情況：
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named sqlite
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:
一、升級或卸載Python導致：
1、查看已安裝python的版本，可能是當前系統存在多個python導致 [root@test ~]# whereis python python: /usr/bin/python2.6 /usr/bin/python /usr/bin/python2.6-config /usr/lib/python2.6 /usr/lib64/python2.6 /usr/include/python2.6 /usr/share/man/man1/python.1.gz [root@test ~]# vi /usr/bin/yum 將 #!/usr/bin/python 修改爲 #!/usr/bin/python2.6 如果是源代碼安裝的，默認路徑是/usr/local/bin/python2.6,做個軟鏈接即可 rm -rf /usr/bin/python ln -s /usr/local/bin/python2.6 /usr/bin/python
二、完全重裝python和yum
1、刪除現有Python [root@test ~]# rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps ##強制刪除已安裝程序及其關聯 [root@test ~]# whereis python |xargs rm -frv ##刪除所有殘餘文件 ##xargs，允許你對輸出執行其他某些命令 [root@test ~]# whereis python ##驗證刪除，返回無結果 2、刪除現有的yum [root@test ~]# rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps [root@test ~]# whereis yum |xargs rm -frv 3、從http://mirrors.ustc.edu.cn/centos/6.4/os/x86_64/Packages/下載相應的包 python-2.6.6-36.el6.x86_64.rpm python-devel-2.6.6-36.el6.x86_64.rpm python-libs-2.6.6-36.el6.x86_64.rpm python-pycurl-7.19.0-8.el6.x86_64.rpm python-setuptools-0.6.10-3.el6.noarch.rpm python-urlgrabber-3.9.1-8.el6.noarch.rpm python-iniparse-0.3.1-2.1.el6.noarch.rpm rpm-python-4.8.0-32.el6.x86_64.rpm yum-3.2.29-40.el6.centos.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-utils-1.1.30-14.el6.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm yum-plugin-protectbase-1.1.30-14.el6.noarch.rpm yum-plugin-aliases-1.1.30-14.el6.noarch.rpm yum-plugin-downloadonly-1.1.30-14.el6.noarch.rpm 由於源中版本會更新，具體請查看URL中的版本再下載下來！ [root@test ~]# rpm -Uvh --replacepkgs python*.rpm [root@test ~]# rpm -Uvh --replacepkgs rpm-python*.rpm yum*.rpm 可能之間還需要zlib和zlib-devel包，根據情況下載並安裝！
三、運行python進行測試
[root@test ~]# python Python 2.6.6 (r266:84292, Feb 22 2013, 00:00:18) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import yum >>> 如上，要是什麼都沒報，則說明OK啦~
