este puede ser exactamente el mismo problema para mí: MongoDB/React Error: listen EADDRINUSE: dirección ya en uso ::: 5000

Probé el método "npx kill-port 5000", y dice "Proceso en el puerto 5000 eliminado". Sin embargo, ejecuto "npm start" nuevamente, solo me da el mismo error.

aquí está mi servidor index.js

 import express from "express"; import bodyParser from "body-parser"; import mongoose from "mongoose"; import cors from "cors"; const app = express(); app.use(bodyParser.json({ limit: "30mb", extended: true })); app.use(bodyParser.urlencoded({ limit: "30mb", extended: true })); app.use(cors()); const CONNECTION_URL = 'mongodb+srv://weiz:123456wz@cluster0.s6fc6.mongodb.net/?retryWrites=true&w=majority'; const PORT = process.env.PORT || 5000; mongoose.connect(CONNECTION_URL, { useNewUrlParser: true, useUnifiedTopology: true }) .then(() => app.listen(PORT, () => console.log("Server running on port: 5000"))) //useless .catch((error) => console.log(error.message)); mongoose.connect(CONNECTION_URL).then(() => { console.log('...') });

aquí está mi error
