离子2-在使用npm install安装node_modules时出错？
我已经安装了最新的Node JS（V8.1.0） ，Ionic和Cordova然后尝试使用npm install命令安装node_modules ，在使用ionic start myApp tabs卡创build的离子演示选项卡项目中，出现以下错误。 我正在使用Windows 10 Pro 。 我已经尝试了很多，但还没有解决这个问题。 任何帮助将不胜感激。

尝试与Node.js V6，它应该工作。 这是因为Node Sass v4.5.0不支持Node.js v8
您可以在此查看支持的Node Sass v4.5.0环境： https ： //github.com/sass/node-sass/releases/tag/v4.5.0
更改为node-sass 4.5.3，因为它修复了节点8上的错误安装https://github.com/sass/node-sass/releases
- 移除package.json中的（webpack，sass-loader / less-loader和node-sass）条目。
- 删除node_modules文件夹
- 安装“ npm install sass-loader node-sass webpack ”。
这对我有效。
