Electron builder 应用程序在安装更新后需要很长时间才能打开

Question

下载完成并安装应用程序后，我的应用程序需要很长时间才能再次启动。应用程序本身只需要 2 秒即可打开，但更新后，即运行

autoUpdater.quitAndInstall(true,true);

后，应用程序将关闭，然后需要大约 50 秒才能再次打开。对于良好的用户体验而言，这太长了。

将 Angular 与带有 Windows 和 S3 的 NSIS 目标结合使用。

  "scripts": {

}

注意：files 参数中的文件列表很长的原因是，Electron 构建器及其所有依赖项都会被复制到用于打包 Electron 应用程序的目录中。

main.js 中的更新程序代码

autoUpdater.on('error', (error) => {
  dialog.showErrorBox('Error: ', error == null ? "unknown" : (error.stack || error).toString())
})

autoUpdater.on('update-available', () => {
  dialog.showMessageBox({
    type: 'info',
    title: 'Found Updates',
    message: 'Found updates, do you want update now?',
    buttons: ['Sure', 'No']
  }).then((buttonIndex) => {
    if (buttonIndex === 0) {
      autoUpdater.downloadUpdate()
    }
    else {
      updater.enabled = true
      updater = null
    }
  })
})

autoUpdater.on('update-not-available', () => {
  dialog.showMessageBox({
    title: 'No Updates',
    message: 'Current version is up-to-date.'
  })
  updater.enabled = true
  updater = null
})

autoUpdater.on('update-downloaded', () => {
  dialog.showMessageBox({
    title: 'Install Updates',
    message: 'Updates downloaded, application will be quit for update...'
  }).then(() => {
    autoUpdater.quitAndInstall(true, true)
  })
})

因此，运行

autoUpdater.quitAndInstall(true, true)

后，应用程序将关闭、卸载、安装新更新并成功重新启动。然而，完成这一切所需的时间太长了。如果我要手动卸载该应用程序，重新安装并自己启动该应用程序，则不会花费那么长时间。我可以做些什么来减少时间吗？

对于 MonsterWriter 我是这样“解决”的：

  alert("The app will close now and restart automatically after the update is installed successfully. Don't be concerned; this process may take up to 1 minute.");
  mw.installAndRestart();

代码在渲染进程内，mw.installAndRestart向主进程发送信号来调用执行重启：

  ipcMain.handle("installAndRestart", () => {
    setImmediate(() => {
      autoUpdater.quitAndInstall(true, true);
    });
  });
