一、報錯信息以下:python
[sybase@localhost yum.repos.d]$ wget http://mirrors.163.com/.help/CentOS-Base-163.repo --2015-06-01 14:29:26-- http://mirrors.163.com/.help/CentOS-Base-163.repo Resolving mirrors.163.com... 123.58.173.186, 123.58.173.185 Connecting to mirrors.163.com|123.58.173.186|:80... connected. HTTP request sent, awaiting response... 404 Not Found
錯誤緣由:錯誤信息描述爲 yum 所依賴的python 不相符,請安裝相對應的python便可linux
二、執行yum查看信息shell
[centos
sybase@localhost log]$ yum 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: 2.7.8 (default, Apr 6 2015, 15:26:40) [GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
提示當前版本是2.7.8可能版本不匹配。沒有yum依賴的包。python2.7
三、查看yum版本ide
[sybase@localhost log]$ rpm -qa|grep yum yum-plugin-security-1.1.30-30.el6.noarch anaconda-yum-plugins-1.0-5.1.el6.noarch yum-3.2.29-60.el6.centos.noarch yum-metadata-parser-1.1.2-16.el6.x86_64 yum-plugin-fastestmirror-1.1.30-30.el6.noarch yum-utils-1.1.30-30.el6.noarch PackageKit-yum-0.5.8-23.el6.x86_64
四、查看python版本
ui
[sybase@localhost log]$ whereis python python: /usr/bin/python2.6 /usr/bin/python2.6-config /usr/bin/python /usr/lib/python2.6 /usr/lib64/python2.6 /usr/local/bin/python2.7 /usr/local/bin/python2.7-config /usr/local/bin/python /usr/local/lib/python2.7 /usr/include/python2.6 /usr/local/python2.7 /usr/share/man/man1/python.1.gz
果真裝了兩個版本pythonthis
五、執行python,查看到使用2.7.8的版本url
[sybase@localhost ~]$ python Python 2.7.8 (default, Apr 6 2015, 15:26:40) [GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
六、猜想yum調用了高版本的python。.net
七、解決方法:
查找yum文件,並編輯此py文件
[root@develop local]# which yum
/usr/bin/yum
[root@develop local]# vi /usr/bin/yum
將
#!/usr/bin/python
改成:
#!/usr/bin/python2.6
而後保存OK.
補充:yum基於python寫的。
