【问题描述】:
我刚刚从这里 https://github.com/facebookincubator/create-react-app 安装了这个 Create React Apps 程序,我已经下载了所有文件,我可以编辑 App.js 文件,但我已经为网站制作了一些 html 文件,我想知道如何将 App.js 文件链接到我当前的文件。给定 Index.html 上的 html 显示未使用 <script> 元素。这是完整的html代码:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="theme-color" content="#000000">
<!--
manifest.json provides metadata used when your web app is added to the
homescreen on Android. See https://developers.google.com/web/fundamentals/engage-and-retain/web-app-manifest/
-->
<link rel="manifest" href="%PUBLIC_URL%/manifest.json">
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
<!--
Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.

<title>React App</title>
</head>
<body>
<noscript>
You need to enable JavaScript to run this app.

<div id="root"></div>
<!--
This HTML file is a template.
If you open it directly in the browser, you will see an empty page.
You can add webfonts, meta tags, or analytics to this file.
The build step will place the bundled scripts into the <body> tag.
To begin the development, run `npm start` or `yarn start`.
To create a production bundle, use `npm run build` or `yarn build`.

您是否阅读了上面写着的通知,请运行
npm start或yarn start。要创建生产包,请使用npm run build或yarn build。
