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
报错：
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
或者
[djuser@localhost ~]$ mkvirtualenv py3test

ERROR: unknown command "installl" - maybe you meant "install"

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.

You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the ‘pip install --upgrade pip‘ command.
(py3test) [djuser@localhost ~]$ cd pippackage/
(py3test) [djuser@localhost pippackage]$ ll

(py3test) [djuser@localhost ~]$ tar -cvf pippack.tar pippackage/
打包后 传到服务器上
解压后执行
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。
