Hi, when i run 'npx tsc', I also received an errors like "Invalid module name in augmentation. Module 'koa' resolves to an untyped module at 'xxxxxxxxx/node_modules/koa/lib/application.js', which cannot be augmented"

Demo

demo.ts


import Koa from 'koa';
import Router from "koa-router";
import koaBody from 'koa-body';

const router = new Router() const app = new Koa();

app.use(koaBody()).use(router.routes());

app.listen(3000)

$ npx tsc demo.ts

## result
