同样是临时维护老项目，执行构建打包命令，例如 npm run build:prod 时报错如下：

ERROR in ./~/css-loader?{"minimize":true,"sourceMap":true}!./~/sass-loader/lib/loader.js?{"sourceMap":true}!./src/styles/index.scss
Module build failed: Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (83)
For more information on which environments are supported please see:
https://github.com/sass/node-sass/releases/tag/v4.11.0
    at module.exports 
......

按道理之前应该是没问题，根据提示可能也是 sass 同当前 node 的环境版本不兼容，当前node 版本为 14.1.0，执行操作：

npm uninstall --save node-sass 
cnpm install --save--dev node-sass

搞定！
