场景：

安装paramiko 时最后提示安装成功
Using /usr/lib64/python2.6/site-packages/pyparsing-2.2.0-py2.6.egg
Finished processing dependencies for paramiko==2.3.1
测试paramiko 是否可用，发现报如下错误：
>>> import paramiko
/usr/lib64/python2.6/site-packages/cryptography-1.8.1-py2.6-linux-x86_64.egg/cryptography/__init__.py:26: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of cryptography will drop support for Python 2.6
  DeprecationWarning

解决方法：

卸载安装的ansible，重新安装ansible即可
因为测试环境没有ansible包，所以下面直接安装ansible包
yum -y install ansible
