报错原因是本地缺少python环境

首先执行npm install -g node-gyp 全局安装node-gyp

执行node-gyp list，若提示需要node-gyp install, 再次执行node-gyp install

执行 npm install --global --production windows-build-tools安装python环境

*如果执行失败可能是由于npm版本过高，降低npm版本到6(安装完以后可升回来)或使用cnpm进行安装

安装成功提示后，注意安装的python信息(有可能是python2.7的子版本，需要注意)

安装成功后，需要执行一下两步

1. 环境变量设置

在Path行添加安装路径 eg:C:\Users\.windows-build-tools\python27

2.cmd设置npm config set python python2.7.15（我的是2.7.15，要设置完整版本号才行）

此时cmd中执行python，会显示python信息

eg:

Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>>

这样就是python已安装成功

下面正常重新执行npm install就行
