我正在创建一个项目，并使用nodejs表示后端. 一切正常，但是当我在文件中进行任何更改时，由于以下错误，nodemon无法重新启动服务器:

I'm creating a project and using nodejs, express for the backend. Everything works fine but as I make any change in the file, nodemon is unable to restart the server due to following error:

Error: listen EADDRINUSE: address already in use :::5000

index.js:

const express = require("express"); const morgan = require("morgan"); const mongoose = require("mongoose"); const cookieParser = require("cookie-parser"); const session = require("express-session"); const FileStore = require("session-file-store")(session); const dotenv = require("dotenv"); var passport = require("passport"); dotenv.config(); const PORT = process.env.PORT || 5000; const app = express(); ..... app.listen(PORT, () => console.log(`Server listening on port ${PORT}!`));

package.json

{ "name": "chat-app-backend", "version": "0.0.0", "private": true, "scripts": { "start": "node index.js", "dev": "nodemon --ignore 'sessions/' index.js" }, "dependencies": { "bcryptjs": "^2.4.3", "cookie-parser": "^1.4.5", "cors": "^2.8.5", "debug": "~2.6.9", "dotenv": "^8.2.0", "express": "~4.16.0", "express-session": "^1.17.0", "http-errors": "~1.6.2", "jade": "~1.11.0", "jsonwebtoken": "^8.5.1", "mongoose": "^5.9.4", "morgan": "~1.9.0", "passport": "^0.4.1", "passport-jwt": "^4.0.0", "passport-local": "^1.0.0", "passport-local-mongoose": "^6.0.1", "session-file-store": "^1.4.0", "uuid": "^7.0.2" }, "devDependencies": { "nodemon": "^2.0.2" } }

我必须每次都从终端显式终止服务器，这不是最佳解决方案. 我尝试了几种方法，但是都没有用.甚至在nodemon GitHub问题页面上发现了一些问题，但是我也找不到任何东西.

I've to explicitly kill the server from the terminal every time, which is not the optimal solution. I tried several things, but none are working. Even found some issue in nodemon GitHub issue page, but there also I couldn't find anything.

即使服务器正在关闭服务器，我也要添加 lsof -i:5000 的输出-节点31625 rishav 20u IPv6 5300049 0t0 TCP *:5000(LISTEN )

I'm also adding the output of lsof -i:5000, even if server I'm closing the server - node 31625 rishav 20u IPv6 5300049 0t0 TCP *:5000 (LISTEN)

推荐答案

我遇到了同样的情况.如果您使用的是Visual Studio Code，请检查您的终端.您可能还有其他已经在运行节点服务器的终端实例.

I had the same situation. If you are using Visual Studio Code, check your terminals. You might have other instances of the terminal that is already running your node server.
