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文件解决：添加
{
test: /\.js$/i,
loader: 'babel-loader',
include: [

resolve('src'),

resolve('test'),

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

resolve('src'),

resolve('test'),

resolve('node_modules/element-ui/src'),

resolve('node_modules/element-ui/packages')
],

{test: /\.(eot|woff|ttf)$/, loader: "file-loader" }
{test: /\.(eot|woff|ttf)$/, 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'}以上这篇解决vue2中使用elementUi打包报错的问题就是小编分享给大家的全部内容了，希望能给大家一个参考。
