1.当前环境版本：

npm -v 6.1.0

node -v v10.0.0

mac 64bit 

2. ionic start –pro-id e24ace68 创建项目出错：

3. 尝试解决方式

npm uninstall –save node-sass  

npm install –save node-sass

本地预览：

ionic serve

仍然报错！ 

bash-3.2# ionic serve -cError: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (64)

For more information on which environments are supported please see:https://github.com/sass/node-sass/releases/tag/v4.7.0   at module.exports(/Users/richardparry/ionicapps/

app-scripts
/node_modules/node-sass/lib/binding.js:13:13)    at Object. (/Users/richardparry/ionic apps/app-scripts/node_modules/node-sass/lib/index.js:14:35)

详细部分随便抓取的，注意删除线部分。仔细查看node app-scripts 内同样引用了node-sass . 版本为4.7.0.

难怪项目下 node_modules node-sass 已经变为4.9.0 .还是出错。

知道问题所在了！同样的操作 app-scripts 下 

npm uninstall –save node-sass  

npm install –save node-sass

项目下 iconic serve 

OK！！！
