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

bash 复制代码 
  "devDependencies": {
    "node-sass": "4.14.1",
    "sass-loader": "10.1.0"
  },

设置镜像

bash 复制代码 
// 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

bash 复制代码 
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

bash 复制代码 
npm uninstall node-sass
npm install sass -i

最后

bash 复制代码 
npm install
