场景：内网服务器不能上外网（代理也不通！），
之前安装了PYTHON的几个安装包，但不是知道为什么无法使用PARAMIKO这个模块
在导入 from cryptography.hazmat.bindings._openssl import ffi, lib 的时候会
报错：
from cryptography.hazmat.bindings._openssl import ffi, lib
ImportError: /usr/local/python36/lib/python3.6/site-packages/cryptography-2.2.2-py3.6-linux-x86_64.egg/cryptography/hazmat/bindings/_openssl.abi3.so: undefined symbol: d2i_DHxparams
找了好多资料都没有解决，没办法只好放弃原有的安装方式，之前是一个个手动下载模块，传到内网服务器后 通过PYTHON SETUP.PY INSTALL 安装。
现在打算在外网通过PIP 下载模块，再打包到内网服务器，然后利用pip安装，这样可以避免模块之间依赖的问题
注：以下步骤是安装单个包的，下例子以安装paramiko包（较多依赖）说明
步骤说明：
1、使用pip download 命令下载wheel文件至下载目录~/pippackage目录下
pip install paramiko --download ~/pippackage/
或者
[root@master pippackage]# pip download paramiko --src ./
[djuser@localhost ~]$ mkvirtualenv py3test

DEPRECATION: pip install --download has been deprecated and will be removed in the future. Pip now has a download command that should be used instead.

打包后 传到服务器上
解压后执行
pip install paramiko-2.4.1-py2.py3-none-any.whl --no-index --find-links=~/pippackage/
安装完成 PARAMIKO 模块就可以正常使用 也没有再报错
原博主有加 --user 参数，但是我加了之后不能执行，不知道为什么，暂时不考虑了。
