element-ui1.x升2.x的教程

package.json 做一下修改

"dependencies": {
  	"element-ui": "2.0.9",
    "vue": "2.5.2",
    "vue-router": "3.0.1",
    "vuex": "3.0.0",

"devDependencies": {
  	"vue-class-component": "^6.0.0",
    "vue-loader": "^13.3.0",
    "vue-property-decorator": "^6.0.0",
    "vue-template-compiler": "2.5.2",

main.js修改引用先后 和CSS路径

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import App from './App.vue' //这里要把App的引用顺序放到最后

注意 ！先把node_modules 文件删了保险点。
