ERROR Error: CSS minification error: Expected a pseudo-class or pseudo-element.. File: static/css/chunk-54dad19c.4031b68b.css

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

解决办法：
删除vue-cli 自带的压缩 plugin：OptimizeCssnanoPlugin
// vue.config.js
config.plugins.delete('optimize-css')
