ERROR in xxx.js from UglifyJs 问题 ERROR in app.bundle.js from UglifyJs Unexpected token: name «element», expected: punc «;» [app.bundle.js:106,8] 在用webpack对代码打包的时候报错，在网上找到了类似的答案，还是没有解决我的问题. 能解决大部分问题的链接 https://stackoverflow.com/questions/41254538/error-in-bundle-js-from-uglifyjs http://www.cnblogs.com/aredleave/p/7586911.html https://segmentfault.com/a/1190000011212544 按照以上方法对环境进行重新配置，依然报错！

ERROR in ./src/index.js Module build failed (from ./node_modules/babel-loader/lib/index.js): Error: Cannot find module '@babel/core' babel-loader@8 requires Babel 7.x (the package '@babel/core'). If you'd like to use Babel 6.x ('babel-core'), you should install 'babel-loader@7'. |
报错原因 通过代码报错原因是 babel-loader 版本问题，因为 babel-loader 用的最新的版本，和 UglifyJs 不兼容. 解决方法 通过运行下面代码对babel-loader进行重新安装（低版本）. npm install --save-dev babel-loader@7 通过修改后的package.json配置文件，亲测可以正确打包，无报错现象.
