vue import element-ui css error solution

For component usage, please refer to the official website http://element.eleme.io/#/zh-CN/ component/quickstart

Write the following content in main.js:

import Vue from 'vue'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-default/index.css'
import App from './App.vue'
 
Vue.use(ElementUI)

If you only want to introduce some components, such as Button and Select, then you need to write the following content in main.js ：

import Vue from 'vue'
import { Button, Select } from 'element-ui'
import App from './App.vue'
Vue.component(Button.name, Button)
Vue.component(Select.name, Select)
/* 或写为
* Vue.use(Button)
* Vue.use(Select)
* /

Install element-ui

cnpm i element-ui@1.3.7 （@为固定版本）

It is recommended to fix the versions of vue and element-ui to avoid conflicts after future version upgrades

Introduce element-ui

Introduce element-ui in app.vue, and then you can use it in any other page

cnpm install style-loader --save-dev
cnpm install css-loader --save-dev
cnpm install file-loader --save-dev
{
test: /\.css$/,
include: [?
/src/,//表示在src目录下的css需要编译?
'/node_modules/element-ui/lib/' //增加此项?
],?
loader: 'style-loader!css-loader'
},（配置加上这个一般不会出错）

Then introduce and register the

webpack1 version in main.js

test:/\.css$/,
loaders:['style','css']

It turns out that the vue template can only have one root object

So if you want to have normal effects, you should use a div or other tags to wrap all the elements

<template>
    <div>
        <el-button type="primary">haha1</el-button>
        <div>hahhaa</div>
        <el-input type="text" placeholder="测试一下"></el-input>
        <h1>{{test1}}</h1>
    </div>
</template>
