1、暂时解决办法

webpack.prod.conf.js

//const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')

解决办法，暂时注释掉
//const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')
//new OptimizeCSSPlugin({
// cssProcessorOptions: config.build.productionSourceMap
//? { safe: true, map: { inline: false } }
// : { safe: true }
//}),
