解决vue2中使用elementUi打包报错的问题

bug1.找不到element-ui/lib/theme-default/index.css

解决：修改路径为 element-ui/lib/theme-chalk/index.css

原因：elementUi升级时遗留bug

bug2: ERROR in static/js/app.77ab8a3664d32f2b9c76.js from UglifyJs

Unexpected token: operator (>) [./~/element-ui/src/mixins/emitter.js:2,0][assets/js/0.498ce690b229694d8858.js:3947,32

解决：打开build目录下webpack.base.conf.js文件

添加

{
 test: /\.js$/i,
 loader: 'babel-loader',
 include: [
  resolve('src'),
  resolve('test'),
  resolve('node_modules/element-ui/src/mixins/emitter.js'),
 ],
},

若重复build不断有类似错误，添加

 test: /\.js$/i,
 loader: 'babel-loader',
 include: [
  resolve('src'),
  resolve('test'),
  resolve('node_modules/element-ui/src'),
  resolve('node_modules/element-ui/packages')
 ],
},

补充知识：vue脚手架加载element-ui报错的解决方法

引入 import 'element-ui/lib/theme-chalk/index.css' 后

各种报错，解决方法

1、cnpm install css-loader style-loader file-loader -D

2、 在webpack.config.js中增加一行rules

{test: /\.(eot|woff|ttf)$/, loader: "file-loader" }

3、npm run dev

注意： {test: /\.css$/,loader: 'style-loader!css-loader'}这一行不必添加，我加上这一行后反而运行错误，这样写也不行 {test: /\.css$/,loader: 'style!css'}
