Deno Uncaught AddrInUse：每个套接字地址（协议/网络地址/端口）通常只允许使用一种。 （操作系统错误10048）

Question

当我尝试运行我的Deno文件时，我得到了os error 10048，如何解决该错误？谢谢

 import { Application } from 'https://deno.land/x/oak/mod.ts'

const app = new Application();
const port = 3000;

app.use((ctx) => {
    ctx.response.body = "Hello World"
})

app.listen({ port })
console.log(`localhost:${port}`)

我尝试运行我的Deno文件，但出现此错误

D:\Deno Documentation\deno3>deno run --allow-net ./server.js
localhost:3000
error: Uncaught AddrInUse: Only one usage of each socket address (protocol/network address/port) is normally permitted. (os error 10048)

Answer 1

您有另一个程序正在监听端口3000，将该端口更改为未使用的端口，或者杀死正在3000上运行的程序。
