当项目npm run start时node-sass报错，报错信息如下： Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (93) For more information on which environments are supported please see:
此时只需做如下几步就可以完美解决：
cnpm install node-sass@4.14.1
npm install
npm update node-sass
npm rebuild node-sass
npm install --save-dev node-sass
接下来就可以通过npm run start完美启动项目了
