解决方案

1.装置node-gyp
npm install -g node-gyp
2.装置python

举荐装置2.7版本（自行抉择32位或者64位装置）：
https://www.python.org/downlo...

如果官网下载速度很慢，能够应用另一种装置形式

以管理员身份执行

npm install --global --production windows-build-tools

装置实现后会在C:WindowsSystem32里找到一个名为.windows-build-tools的文件夹

能够间接依照这个目录配置环境，为了不便，我抉择将python27重装到D盘，点击python-2.7.15.amd64.msi抉择

移除之后再点击setup程序，这次能够间接装置


装置胜利后，在命令行界面输出python测试是否装置胜利

3.配置环境变量

环境变量->零碎环境变量->Path

4.npm 配置
npm config set python "D:\Python27\python.exe"npm config set node_gyp "D:\nodejs\node_modules\npm\node_modules\node-gyp\bin\node-gyp.js"

配置胜利后，再次运行npm install就不会报错了
