今天差点没有坑死我，package.json里面
然后我打包解决element-ui的转译问题时，发现node_modules里面
被坑的我的心都死了，不过还好最后是解决了
module: { ??... ?????{ ???????test: /\.js$/, ???????loader: ‘babel-loader‘,//注意elementUI的源码使用ES6需要解析 ???????include: [resolve(‘src‘), resolve(‘test‘),resolve(‘/node_modules/_element-ui@1.4.10@element-ui/src‘),resolve(‘/node_modules/_element-ui@1.4.10@element-ui/packages‘)] ?????}, ?????...
npm run build 后
ERROR in static/js/0.0143a4d9ad92d5c7f658.js from UglifyJsUnexpected token: punc (() [./~/_element-ui@1.4.10@element-ui/packages/row/src/row.js:24,0][static/js/0.0143a4d9ad92d5c7f658.js:524,9]ERROR in static/js/1.c6586324bf2fd251ec7b.js from UglifyJsUnexpected token: punc (() [./~/_element-ui@1.4.10@element-ui/packages/row/src/row.js:24,0][static/js/1.c6586324bf2fd251ec7b.js:539,9]ERROR in static/js/2.2b7b58156258c88e9cdf.js from UglifyJsUnexpected token: punc (() [./~/_element-ui@1.4.10@element-ui/packages/row/src/row.js:24,0][static/js/2.2b7b58156258c88e9cdf.js:539,9]ERROR in static/js/8.48d0e6b7d1466b2cb224.js from UglifyJsUnexpected token: operator (>) [./~/_element-ui@1.4.10@element-ui/src/mixins/emitter.js:2,0][static/js/8.48d0e6b7d1466b2cb224.js:89,32]
UglifyJs 一般是 无法解析ES6的问题，在1.4.10 element-ui的包里看来是有ES6的语法了
在build文件夹的 webpack.base.conf.js
看到它，心里安定多了
vue+element-ui打包时候出现 UglifyJs Unexpected token: punc
