Unable to find vcvarsall.bat的解决办法

明年绝对买MAC电脑，这一两天安装paramiko，真是操碎了心。

安装paramiko时报error: Unable to find vcvarsall.bat这种错误，网上找了各种方法啊，解决的办法是下载http://go.microsoft.com/fwlink/?LinkId=691126这个。然后会有段漫长的等待时间，安装完重启后就好了

友提：我的python环境是3.5

Python Version	You will need
3.5 and later	Visual C++ Build Tools 2015 or Visual Studio 2015
3.3 and 3.4	Windows SDK for Windows 7 and .NET 4.0 (Alternatively, Visual Studio 2010 if you have access to it)
