vue项目 vue-cli npm run build 报错 无法生成dist文件夹 求教如何解决

Question

下面是执行npm run build命令时完整的报错信息
好像是因为uglifyjs-webpack-plugin这个模块，看了下之前的项目没有找到这个模块，这次新项目好像自动生成了这个

module.js:549

throw err;
^

Error: Cannot find module 'uglifyjs-webpack-plugin'

Answer 1

uglifyjs-webpack-plugin没找到。
你的webopack配置文件和webpack版本可以发出来看下，就知道哪出问题了
