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)

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
