python(abi) = 2.6
Available: python-2.6.6-51.el6.i686 (base)

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

解决方法如下：

yum clean all
rpm --rebuilddb
yum update

或者换一个yum源也行 添加源的方法 参见： http://blog.youkuaiyun.com/zqtsx/article/details/39207069 
删掉原来的需要的包，重新安装

如果上诉方法不能解决就是 软件 源文件包 不存在的问题了，直接添加第三方yum 源地址即可解决 方法 参见 摘取天上星的 CENTOS添加源 的文章 http://blog.youkuaiyun.com/zqtsx/article/details/39207069
