Web 应用程序清单不符合可安装性要求

Question

我尝试制作一个渐进式网络应用程序，但 Lighthouse 说，我没有足够的图标，这是 Lighthouse 的问题：

Web app manifest does not meet the installability requirementsFailures: Manifest does not have a PNG icon of at least 144px.

Is not configured for a custom splash screenFailures: Manifest does not have a PNG icon of at least 512px.

快速可靠的“选项卡”中有两个错误，但我认为这应该无关紧要？

这是我的 Manifest.json:

{
  "name": "PWA Test Tutorial",
  "short_name": "PWA",
  "start_url": ".",
  "background_color": "green",
  "theme_color": "red",
  "display": "standalone",
  "prefer_related_applications": "false",
  "icons": [
            {
              "src": "testLOGO.png",
              "sizes": "512x512",
              "type": "images/png"
            },
            {
              "src": "192.png",
              "sizes": "192x192",
              "type": "images/png"
            },
            {
              "src": "512.png",
              "sizes": "512x512",
              "type": "images/png",
              "purpose": "maskable"
            }
          ]

}

我的问题在哪里？您需要更多信息吗？感谢您的关注

您的图标的 type 应该是 image/png（没有“s”）
