我正在尝试恢复我一年半前编写的旧 React 应用程序。
我克隆了它并安装了所有依赖项,但是当我执行“npm start”时,它只会加载一个空白页面并抛出错误:
“URIError:无法解码参数'///%PUBLIC_URL%/manifest.json'”
老实说,我不确定从这里去哪里。
这是我的 package.json 的样子:

{
"name": "nosmallstreamer",
"version": "1.0.0",
"description": "This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).",
"main": "index.js",
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
"repository": {
"type": "git",
"url": "git+https://github.com/chaselancaster/nosmallstreamer-frontend.git"
},
"author": "",
"license": "ISC",
"bugs": {
"url": "https://github.com/chaselancaster/nosmallstreamer-frontend/issues"
},
"homepage": "https://github.com/chaselancaster/nosmallstreamer-frontend#readme",
"dependencies": {
"react": "^17.0.1",
"react-dom": "^17.0.1",
"react-router-dom": "^5.2.0",
"react-scripts": "^4.0.0"
},
"browserslist": {
"production": [
">0.2%",
"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
这是我的 index.html 在 public 文件夹中的样子:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<!-- <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" /> -->
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<!--
manifest.json provides metadata used when your web app is installed on a
user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
-->
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<!--
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.</noscript>
<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`.
-->
</body>
</html>
这是我的 manifest.json 在 public 文件夹中的样子:
{
"short_name": "React App",
"name": "Create React App Sample",
"icons": [
{
"src": "favicon.ico",
"sizes": "64x64 32x32 24x24 16x16",
"type": "image/x-icon"
}
],
"start_url": ".",
"display": "standalone",
"theme_color": "#000000",
"background_color": "#ffffff"
}
任何帮助表示赞赏!

最佳答案

尝试更改您的 homepage在您的 package.json文件到:"/"而不是使用您的 GitHub 存储库的 URL。 react-scripts run (这是 npm start 运行的)似乎使用来自 homepage 的域作为服务应用程序的根。
