一、使用webpack初始化一个项目

vue init webpack-simple vueadmin

使用webpacck-simple模板创建项目，

$ vue init webpack-simple vueadmin

? Project name vueadmin
? Project description a project by vue2.0
? Author kingQQ673575951
? License MIT
? Use sass? No

   vue-cli · Generated "vueadmin".

   To get started:

     cd vueadmin
     npm install
     npm run dev

二、引入elementui

http://element.eleme.io/#/zh-CN

npm i element-ui -S

main.js

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import App from './App.vue'

Vue.use(ElementUI)

注意这个错误：

Failed to compile.

./node_modules/_element-ui@2.2.0@element-ui/lib/theme-chalk/fonts/element-icons.ttf Module parse failed: Unexpected character '' (1:0) You may need an appropriate loader to handle this file type. (Source code omitted for this binary file) @ ./node_modules/_css-loader@0.28.10@css-loader!./node_modules/_element-ui@2.2.0@element-ui/lib/theme-chalk/index.css 7:327-363 @ ./node_modules/_element-ui@2.2.0@element-ui/lib/theme-chalk/index.css @ ./src/main.js @ multi ./node_modules/_webpack-dev-server@2.11.2@webpack-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js

错误的原因是element-ui里面的图标是字体，需要使用一个loader处理

修改webpack.config.js 添加一个loader

//element ui里面有字体文件 必须引入
     { test: /\.(eot|woff|ttf)$/, loader: 'file-loader' },

总结

1. 注意引入elementui后的错误

webpack.config.js

var path = require('path')
var webpack = require('webpack')

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),

        options: {
          loaders: {

          // other vue-loader options go here
        }
      },
       //element ui里面有字体文件 必须引入
