我对React完全陌生。但是我在加载react dom和在控制台中遇到错误browser.js:5844 Failed to load file:///C:/..../my-app/script.js: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.---- browser.js:5900
我正在使用从此CDN下载的reactjs版本
<script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
<body>
<div id="root"></div>
<script src="react.js"></script>
<script src="react-dom.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.24/browser.js"></script>

'use strict';
class Hello extends React.Component {
render() {
return (
<h1>Hello WOrld!</h1>
);
}
}
ReactDOM.render(
Hello,
document.getElementById('root')
);
但是分解index.html不会显示任何内容。它为空白，并且控制台显示上述错误
