Question

电子：6.0.9

电子更新器：4.1.2

我致电autoUpdater.checkForUpdates时电子应用程序崩溃了没有互联网连接

应用程序甚至被尝试捕获块包围也崩溃了

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

在电子琴上运行此测试（使用autoUpdater.setFeedURL（“ https://example.com/”））

Error: Error: net::ERR_NAME_NOT_RESOLVED

Electron exited with code 0.

Answer 1

#1是一个异步函数，它返回一个Promise。您无法使用#2捕获这些错误。

这是您捕获错误的方法：

autoUpdater.checkForUpdates()
