Question

我尝试运行后端服务器，但是当我在 cmd 中运行命令 node backend/server.js 时，出现此错误：

D:\theshoppingcart>node backend/server.js
events.js:187
      throw er; // Unhandled 'error' event
      ^

Error: listen EACCES: permission denied 8085;

    at listenInCluster (net.js:1349:12)

Emitted 'error' event on Server instance at:

  code: 'EACCES',
  errno: 'EACCES',
  syscall: 'listen',
  address: '8085;',
  port: -1
}

这是我的后端/server.js 文件：

require('dotenv').config()
const express = require("express");
const connectDB = require('./config/db');

connectDB();

const app = express();

const PORT = process.env.PORT || 8085;

app.listen(PORT, ()=> console.log(`server running on port ${PORT}`));

我遇到了同样的问题，你应该去掉分号；来自 .env 文件。这对我有用。

错误：听 EACCES：权限被拒绝 8085；
