1、错误描述

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly95b3VoYWlkb25nLmJsb2cuY3Nkbi5uZXQ_size_16_color_FFFFFF_t_70

2、错误原因

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(<App />, document.getElementById('root'));
// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: https://bit.ly/CRA-PWA
serviceWorker.unregister();
import React from 'react';
import ReactDOM from 'react-dom';
import Column2D from './components/Column2D.js'
import logo from './logo.svg';
import './App.css';
function App() {
  return (
   <Column2D/>,
     document.getElementBy("root")
  );
}
export default App;
 在调用FusionCharts图形组件时，直接将其装载到index.html中的ID为root的div中，出现了报错（如果是一个集合的话，需要使用一个数组来代替）

3、解决办法

import React from 'react';
import ReactDOM from 'react-dom';
import Column2D from './components/Column2D.js'
import logo from './logo.svg';
import './App.css';
function App() {
  return (
   <Column2D/>
  );
}
export default App;
