错误:侦听EACCES:权限被拒绝8085；

Question

我尝试运行后端服务器，但是当我在命令行中运行node backend/server.js命令时，我得到了这个错误：

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

Error: listen EACCES: permission denied 8085;

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

这是我的backend/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}`));

我也遇到了同样的问题，您应该从.env文件中删除分号；。这对我很有效。
