React ie11不兼容 React Ant create-react-app创建

react

用react-app" title="create-react-app">create-react-app创建的项目不支持ie

1、首先npm install react-app-polyfill --save

2、入口文件 index.js 顶部添加，一定是顶部

import 'react-app-polyfill/ie11';

import 'react-app-polyfill/stable';

import React from 'react';

import ReactDOM from 'react-dom';

import App from './App';

import './style.js'

3、在package.json 文件的添加 ie11

"browserslist": {

"production": [

">0.2%",

"not dead",

"not op_mini all",

"ie 11"

"development": [

"last 1 chrome version",

"last 1 firefox version",

"last 1 safari version",

"ie 11"

]

}

4、重新启动，一般还不好用，删除node_modules 重新下载好用好用开心到飞起来。
