    Number one answer is not work for me，i solved the problem by the following step

    1. Add shell on const {app, BrowserWindow} = require('electron')
    1. const {app, BrowserWindow, shell} = require('electron')
    1. Set nativeWindowOpen is true
    1. function createWindow () {
    2.   // Create the browser window.
    3.   const mainWindow = new BrowserWindow({
    4.     width: 1350,
    5.     height: 880,
    6.     webPreferences: {
    7.       nativeWindowOpen: true,
    8.       preload: path.join(__dirname, 'preload.js')
    9.     },
    10.     icon: path.join(__dirname, './img/icon.icns')
    11. })
    1. Add the following listener code
    1.   mainWindow.webContents.on('will-navigate', function(e, reqUrl) {
    2.     let getHost = url=>require('url').parse(url).host;
    3.     let reqHost = getHost(reqUrl);
    4.     let isExternal = reqHost && reqHost !== getHost(wc.getURL());
    5.     if(isExternal) {
    6.       e.preventDefault();
    7.       shell.openExternal(reqUrl, {});
    8.     }
    9.   })
