React 组件不渲染的坑...

组件的标签名必须大写….

import './App.css';import React from 'react';import ShopTitle from './shopTitle/ShopTitle.jsx';console.log(ShopTitle)export default class App extends React.Component{    render(){        return (            <div>                <h1>nihao</h1>                <ShopTitle/>            </div>        )    }}

上面是可以运行的

import './App.css';import React from 'react';import shopTitle from './shopTitle/ShopTitle.jsx';console.log(shopTitle)export default class App extends React.Component{    render(){        return (            <div>                <h1>nihao</h1>                <shopTitle/>            </div>        )    }}

这种就不能运行了,<shopTitle/>不被辨识
