Deno 观察者 | Uncaught AddrInUse：每个套接字地址只有一次使用

Question

当我在保存文件并重新启动 deno watcher 后使用 Deno watcher 时

提出这个问题并在终端中显示：

Watcher File change detected! Restarting!
    error: Uncaught AddrInUse: Only one usage of each socket address (protocol/network address/port) is normally permitted. (os error 10048)
Watcher Process finished. Restarting on file change...

保存 app.ts 后再次在终端中显示以下行：

Watcher File change detected! Restarting!
error: Uncaught AddrInUse: Only one usage of each socket address (protocol/network address/port) is normally permitted. (os error 10048)
    core.runMicrotasks();
         ^

    at processTicksAndRejections (https://deno.land/std@0.164.0/node/_next_tick.ts:62:10)
Watcher Process finished. Restarting on file change...

我的应用程序：

import express, { Express, Request, Response } from "npm:express@4.18";
import { v4 as uuidv4 } from 'npm:uuid@9.0.0';
const app: Express = express();

app.use("/", (_req: Request, res: Response) => {
    res.send(`uuid: ${uuidv4()}.`);
})

app.listen(8000, () => {
    console.log("App Running: http://localhost:8000");
});

使用的命令： deno run --allow-all --watch app.ts

这是 Deno 中的一个错误（参见 https://github.com/denoland/deno/issues/16699#issuecomment-1322854380），并在 Deno v1.28.2 中进行了修补。
