node -v 6.11.2
npm -v 3.10.10
electron -v 1.4.13

windows system arch=ia32

main.js
// 检测更新，在你想要检查更新的时候执行，renderer事件触发后的操作自行编写
function updateHandle(){
let message={
error:'检查更新出错',
checking:'正在检查更新……',
updateAva:'检测到新版本，正在下载……',
updateNotAva:'现在使用的就是最新版本，不用更新',
};
const os = require('os');
autoUpdater.setFeedURL('http://192.168.0.208:7081/outApp/');
autoUpdater.on('error', function(error){
sendUpdateMessage(message.error)
});
autoUpdater.on('checking-for-update', function() {
sendUpdateMessage(message.checking)
});
autoUpdater.on('update-available', function(info) {
sendUpdateMessage(message.updateAva)
});
autoUpdater.on('update-not-available', function(info) {
sendUpdateMessage(message.updateNotAva)
});

// 更新下载进度事件
autoUpdater.on('download-progress', function(progressObj) {
    mainWindow.webContents.send('downloadProgress', progressObj)
})
autoUpdater.on('update-downloaded',

function (event, releaseNotes, releaseName, releaseDate, updateUrl, quitAndUpdate) {
ipcMain.on('isUpdateNow', (e, arg) => {
//some code here to handle event
autoUpdater.quitAndInstall();
})
mainWindow.webContents.send('isUpdateNow')
app.quit();
});

//执行自动更新检查
autoUpdater.checkForUpdates();

Checking for update
update for version 1.6.11 is not available (latest version : 0.0.2, downgrade is disallowed.)

use English thanks

[develar]

Issue report is not clear for me.

update for version 1.6.11 is not available (latest version : 0.0.2, downgrade is disallowed.)

So, your server returns this data. For what do you use setFeedURL?

[AragornZJF]

ok use electron-builder and electron-updater
The message tips is
`` update for version 1.6.11 is not available (latest version : 0.0.2, downgrade is #disallowed.)

How can I resolve this question ??

[develar]

Your current app version is "1.6.11" (do you run unpacked app or packed?). Latest (returned by your server) is 0.0.2. So, update is disallowed.

[AragornZJF]

thanks my local app version 0.0.1 why show electron version "Your current app version is "1.6.11" ??

[develar]

Please specify electron-updater and electron-builder version. Do you run packed exe or as electron app?

[AragornZJF]

ok thanks.

Latest version (from update server) is not valid semver version: "null 我的这个报错信息大家有了解过吗

不允许降级操作。

笔者发现在检查更新的时候，electron 会把 electron 的版本当作当前应用版本（package.json）。

当前应用是基于 [email protected]，应用版本为1.0.0，而服务器上应用版本低于1.7.5，进而提示不允许降级操作。

这个bug是由于 electron 配置启动地址错误造成的。

把 /.electron-vue/dev-runner.js
中 startElectron
路径 path.join(__dirname, '../dist/electron/main.js')
改成 '.'

startElectron

you a right!so 66666
