公司測試機環境不知道給我卸了什麽包，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 2 3 4 5 6 7 8 |
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 修改為 #!/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 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
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 ##刪除所有殘余文件 ##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
| 1 2 3 4 5 6 7 |
[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，要是什麽都沒報，則說明OK啦~
