node.js - MacOS Catalina - 节点快速应用程序 - http localhost 服务器失败

Question

我最近将我的 MacOS 升级到了 Catalina。尝试使用以下命令启动我的本地 Node Epress 应用程序时：

npm start

我收到此错误：

xxxxx:app xxxx$ npm start

> xxxx@0.0.1 start /Users/xxxxx/Documents/GitHub/xxxxxx/app
> node ./bin/www

/Users/xxxxx/Documents/GitHub/xxxxxx/app/bin/www:76
      throw error;
      ^

在将 MacOS 更新到 Catalina 之前，一切正常。./bin/www如下所示

#!/usr/bin/env node

/**
 * Module dependencies.
 */

var app = require('../app');
var debug = require('debug')('myapp:server');
var http = require('http');

/**
 * Get port from environment and store in Express.
 */

var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);

/**
 * Create HTTP server.
 */

var server = http.createServer(app);

/**
 * Listen on provided port, on all network interfaces.
 */

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);

/**
 * Normalize a port into a number, string, or false.
 */

function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

/**
 * Event listener for HTTP server "error" event.
 */

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  // handle specific listen errors with friendly messages
  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}

/**
 * Event listener for HTTP server "listening" event.
 */

function onListening() {
  var addr = server.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}

更新：

我试图通过生成器生成一个全新的节点快速应用程序 - 也不起作用。

如果我重新启动我的 Mac，如果我在前 30 秒内启动它，服务器就会工作！

在那之后似乎端口被阻塞或什么？

似乎它必须是某种防火墙？

更新：

我尝试使用不同的 http 服务器包 - 完全一样的错误！- 错误：监听 EPROTOTYPE：套接字 0.0.0.0:8080 的协议类型错误

https://www.npmjs.com/package/http-server

https://www.npmjs.com/package/server

问题必须在 MacOS Catalina 中！

更新：

我发现问题一定是防火墙或我的 MAC 上安装的东西。

当我将笔记本电脑与 WIFI 断开连接时，一切正常。
