错误无法读取未定义的属性 'updaterCacheDirName'

Question

我正在尝试创建一个具有自动更新功能的应用程序，但是运行版本搜索

时出现错误

应用程序找到版本，当它即将关闭时我收到此错误

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)
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执行更新功能的位置，并与 Github 存储库中的其他代码进行了检查，但所有代码都与我拥有的代码相同，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

您是否在开发模式下测试过自动更新功能，而无需打包应用程序？

我遇到了同样的错误，以下解决方案对我有用。

看看documentation:

Note that in order to develop/test UI/UX of updating without packaging the application you need to have a file named dev-app-update.yml

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 格式提供 package.json 中的发布属性。

dev-app-update.yml

provider:"github"
owner: "abc"
