解决：
node-sass 问题
node-sass版本需与node版本对应，如下
可在项目根目录文件package.json中查看node-sass版本，没有请忽略
"devDependencies": {
"node-sass": "4.14.1",
"sass-loader": "10.1.0"
},
设置镜像
// 设置国内npm镜像地址
npm config set registry http://registry.npmmirror.com
// 查询npm配置
npm config list
安装编译环境
npm install -g node-gyp
// 在 Windows 上？想要编译原生 Node 模块吗？使用这一行安装构建工具。以管理员身份启动 PowerShell 并运行
npm install --global --production windows-build-tools
https://www.npmjs.com/package/windows-build-tools
卸载安装失败的包，重新安装
npm uninstall node-sass
npm install sass -i
最后
npm install
