对于初学者来说，我为“正常”（非托盘）应用程序构建的程序可以与电子打包程序和此命令一起正常运行

我最近重构了我的代码，所以现在是一个托盘应用程序
所以我有
npx electron-packager . --overwrite --plaorm=darwin --arch=x64 --icon=aicons/1024.icns --prune=true --out=release-builds
这与npm start一起正常工作，但是当我使用电子打包程序构建.app时，出现此错误：
tray = new Tray('icons/elektro.png')
tray.setToolTip('elektro')
我认为问题与用于托盘图标的.png有关。如果我将其更改为.icns格式，则无法通过npm start正常运行。您知道如何解决此问题吗？
我正在使用电子6
答案 0 :(得分：0)
好的，问题与路径有关。看起来微不足道，但是.app文件在大多数情况下都可以正常死掉而没有任何错误。这个问题在任何地方的记录都很少，所以我把它留给任何发现相同问题的人：
const path = require('path');
var iconPath = path.join(__dirname, '/icons/elektro.png') // your png tray icon
let trayIcon = nativeImage.createFromPath(iconPath);
// if needed resize to 16x16 but mac also accepted the 24 icon
// trayIcon = trayIcon.resize({
// width: 16,
// height: 16
// });
tray = new Tray(trayIcon)
