我已经安装了最新的Node JS ( v 8.1.0 )，Ionic和Cordova，然后尝试使用node_modules在使用npm install创建的离子演示标签项目中安装ionic start myApp tabs，我得到了以下错误。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。

尝试使用Node.js v6，它应该可以工作。这是因为Node Sass v4.5.0不支持Node.js v8
您可以在此处查看Node Sass v4.5.0支持的环境：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

这对我有用。
答案 3 :(得分：0)
尝试运行此命令：
npm install --unsafe-perm node-sass
