我正在尝试创建具有自动更新功能的应用程序,但在运行版本搜索时出现错误

该应用程序找到了版本,当它即将关闭时,我收到了这个错误

Error: TypeError: Cannot read property 'updaterCacheDirName' of undefined
    at NsisUpdater.getOrCreateDownloadHelper (C:\Users\neyun\Desktop\app\node_modules\electron-updater\out\AppUpdater.js:659:55)
    at async NsisUpdater.executeDownload (C:\Users\neyun\Desktop\app\node_modules\electron-updater\out\AppUpdater.js:708:36)

我已经检查了我的代码,它在哪里执行更新功能,我用 Github 存储库中的其他代码检查了它,但所有代码都等于我拥有的那个,这是我在应用程序菜单中的代码

const { app, BrowserWindow, ipcMain } = require('electron');
          const { autoUpdater } = require("electron-updater");
          let token = "";
          let v = app.getVersion()
          autoUpdater.allowPrerelease = true;
          autoUpdater.currentVersion = v;
          autoUpdater.logger = log;
          autoUpdater.autoDownload = false
          autoUpdater.setFeedURL({
            "provider": "github",
            "owner": "",
            //"token": token, //deleted 
            "private":true,
            "repo": ""
          });
          autoUpdater.logger.transports.file.level = 'info';
          log.info('App starting...');
          function createWindow () {
            mainWindow = new BrowserWindow({
              width: 800,
              height: 600,
              webPreferences: {
                nodeIntegration: true,
              },
            });
            mainWindow.loadURL(`file://${__dirname}/public/update.html`);
            mainWindow.setMenu(null)
            mainWindow.on('closed', function () {
              mainWindow = null;
            });
            autoUpdater.checkForUpdates();



          }


          createWindow();



          app.on('window-all-closed', function () {
            if (process.platform !== 'darwin') {
              app.quit();
            }
          });

          app.on('activate', function () {
            if (mainWindow === null) {
              createWindow();
            }
          });

          ipcMain.on('app_version', (event) => {
            event.sender.send('app_version', { version: app.getVersion() });
          });

          autoUpdater.on('update-available', () => {
            mainWindow.webContents.send('update_available');
            autoUpdater.downloadUpdate().then((path)=>{
              console.log('download path', path)
            }).catch((e)=>{
              console.log(e)
            })
          });

          autoUpdater.on('update-downloaded', () => {
            autoUpdater.autoInstallOnAppQuit()
          });
          autoUpdater.on('checking-for-update', () => {
            mainWindow.webContents.send('check_update');
          });
          autoUpdater.on('update-not-available', () => {
            mainWindow.webContents.send('not_update');
          });
          ipcMain.on('restart_app', () => {


          });

这是html,无论是否有新版本,都会显示版本和警告

您是否在未打包应用程序的情况下在开发模式下测试了自动更新功能?

我有同样的错误,以下解决方案对我有用。

看看文档

请注意,为了在不打包应用程序的情况下开发/测试更新的 UI/UX,您需要有一个名为 dev-app-update.yml 的文件

在这种情况下,在您的根目录中创建一个“dev-app-update.yml”文件,并以 yaml 格式从您的 package.json 提供您的发布属性。

开发应用程序更新.yml
