使用VSCode运行 npm run build 报错

使用npm run build命令打包后，会自动压缩js、css等代码。从上面的报错信息不难看出，是压缩css代码时出错了

解决方法

找到webpack.prod.conf.js文件，
注释以下代码
//const OptimizeCSSPlugin = require(‘optimize-css-assets-webpack-plugin’)
//new OptimizeCSSPlugin({
// cssProcessorOptions: config.build.productionSourceMap
//? { safe: true, map: { inline: false } }
// : { safe: true }
//}),
