我们在安装一些Python包时，可能会遇到不能安装的问题，提示为缺C++相应的扩展包。提示为“Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools”。

原因是使用pip install 安装的过程中需要c++ 编译，而且有些对编译器依赖有比较高。

经查找，以以下三个方法解决。

一、直接下载对应版本的.whl文件，然后运行pip install xxx.whl进行安装

whl 包的下载地址

https://www.lfd.uci.edu/~gohlke/pythonlibs/
https://pypi.org/project/

二、按照提示去官网下载Visual Studio
https://visualstudio.microsoft.com/zh-hans/downloads/
注意要安装visual studio的C++开发环境。

三、使用Microsoft Visual C++ Build Tools
可以选择visual studio2019中的单个组件，C++ ATL v141生成工具(x86& x64)，也可以安装其他版本的生成工具。如果还不行（实际上我安装了多个版本的，也没有成功），可以选择使用增加C++的桌面开发，但是这样安装量就比较大，相当于安装了Visual Studio。
