无法安装渐进式 Web 应用程序站点:没有可显示的图标
progressive web app site cannot be installed: no icon available to display
我正在构建一个渐进式网络应用程序。我从 create-react-app 的样板文件开始。然后我添加了一个网络应用程序清单。
app/public/manifest.json
{
"short_name": "First Contributions",
"name": "First Contributions",
"icons": [
{
"src": "/android-chrome-192x192.png",
"sizes": "192x192",
"type": "image/png"
},
{
"src": "/android-chrome-256x256.png",
"sizes": "256x256",
"type": "image/png"
}
],
"theme_color": "#ffffff",
"background_color": "#ffffff",
"display": "standalone",
"start_url": "index.html"
}
将此链接到 index.html
app/public/index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">

</head>
<body>
<div id="root"></div>
<script>
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('service-worker.js').catch(function(ex) {
console.warn(ex);
console.warn('(This warning can be safely ignored outside of the production build.)');
});
}
</script>
</body>
</html>
我使用 realfavicongenerator.net
生成图标并将它们放在 public 目录中。
我正在使用 gh-pages
部署我的应用程序。当我尝试 Add to homescreen
时,出现以下错误
- android-chrome-192x192.png:1 GET https://roshanjossey.github.io/android-chrome-192x192.png 404 (Not Found)
- Error while trying to use the following icon from the Manifest: https://roshanjossey.github.io/android-chrome-192x192.png (Download error or resource isn't a valid image)
- Site cannot be installed: no icon available to display
我认为我在图标的 webmanifest 中做错了什么。
您的图标路径引用了根目录。
将"src": "/android-chrome-192x192.png",
更改为"src": "android-chrome-192x192.png",
(开头没有/
)。
