在 vue.config.js 中，设置图标的 PWA 选项以指向您想要的任何图标.具体设置pwa.iconPaths例如:

Inside the vue.config.js set the PWA options for the icons to point to whatever icons you want. Specifically, set pwa.iconPaths for example:

module.exports = {
  pwa: {
    iconPaths: {
       favicon32: 'img/icons/myFavicon.png',
    }
  }
}
