Answer 1

app.on('ready') ...＆＃39; app＆＃39;不是你的快递应用程序。这应该是电子app。

示例：

var app = require('app');
BrowserWindow = require('browser-window');
express = require('express');
expressApp = express();

可以快递使用＆＃39; app＆＃39;变量和电子也使用它。

Answer 2

通常，EADDRINUSE错误意味着您的端口已经被使用（可能是您的快速网络服务器的实例）。也许你的电子应用程序没有正确关闭，你必须手动杀死以杀死正在访问该端口的网络服务器。
