electron - 调用autoUpdater.checkForUpdates时Electron应用程序崩溃

Question

electron : 6.0.9

electron-updater: 4.1.2

调用 autoUpdater.checkForUpdates时 Electron 应用程序崩溃
没有互联网连接

应用程序甚至在 try catch 块中被包围也崩溃了

    try {
        autoUpdater.checkForUpdates();
    } catch(e) {
        logEverywhere('Error, Failed to check for updates!');
    }

Run this test on electron fiddle (with autoUpdater.setFeedURL("https://example.com/"))

autoUpdater.checkForUpdates()是一个返回 promise 的异步函数。您无法使用try catch捕获这些错误。

这是您捕获错误的方式:

autoUpdater.checkForUpdates().catch(err => {
    console.error(`Something went wrong`, err);
});
