系统找不到指定的文件。(操作系统错误2)在Deno中

使用视图引擎模板在Deno中呈现HTML、CSS和静态文件
MyCode：
文件夹结构
-public
-css
-main.css
-js
-app.js
-views
-index.ejs
-server.tsserver.ts
/* Introduction To Rendering HTML,CSS and Static Files inside Deno with View Engine Template */
// Importing Required Files And Packages Here.
import { Application, Router, send } from "https://deno.land/x/oak/mod.ts";
import {
viewEngine,
engineFactory,
adapterFactory,
} from "https://deno.land/x/view_engine/mod.ts";
// Initializing App Here.
const app = new Application();
// Setting Up Ejs Templating Engine Here.
const ejsEngine = engineFactory.getEjsEngine();
const oakAdapter = adapterFactory.getOakAdapter();
// Serving A Static Folder Here.
app.use(async (ctx,next)=>{
await send(ctx,ctx.request.url.pathname,{
root :`${Deno.cwd()}/public`
})
next();
})
// Initializing Router Here.
const router = new Router();
// Defining Routes Here.
router.get("/test", (ctx) => {
ctx.render("views/index.ejs", {
payload: {
text: "test",
},
});
}).get("/", (ctx) => {
ctx.render("views/index.ejs", {
payload: {
text: "<h1>Introduction To Templating Engines In Deno. </h1>",
},
});
});
// MiddleWares Here.
app.use(viewEngine(oakAdapter, ejsEngine));
app.use(router.routes());
app.use(router.allowedMethods());
console.log("Server Started On Port Number 8000.");
await app.listen({ port: 8000 });
// Run : deno run --allow-net --allow-read server.ts视图/index.ejs :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Templating Engines</title>
<link rel="stylesheet" href="/css/main.css" />
<script src="/js/app.js" defer></script>
</head>
<body>
<h1>Welcome To Deno World!</h1>
<div><%- payload.text %></div>
<p id="content"></p>
</body>
</html>public/css/main.css
p{
color:red;
}public/js/app.js
const content = document.getElementById("content");
const getDataJsFile = () => {
content.innerHTML = `
Java script Dummy Text ::::::==>
Lorem ipsum dolor sit amet consectetur adipisicing elit. Nesciunt quaerat
perferendis consectetur doloribus repellendus ullam corrupti explicabo
placeat reprehenderit ad.`;
};
getDataJsFile();当我运行这段代码时，deno运行--允许-net--允许读取server.ts。http://localhost:8000/运行良好，但在http://localhost:8000/test中，我得到了以下错误：
系统找不到指定的文件。Deno

所有对/test路由的获取请求都被静态内容中间件截获，然后将中间件功能转移到通用中间件设置中。
app.use(viewEngine(oakAdapter, ejsEngine));
app.use(router.routes());
app.use(router.allowedMethods());
// Serving A Static Folder Here.
app.use(async (ctx,next)=>{
await send(ctx,ctx.request.url.pathname,{
root :`${Deno.cwd()}/public`
})
next();
