Deno and oak error: TS2315 [ERROR]: Type 'Conn' is not generic - with Deno using oak as server on macOs with basic example code

Question

我正在尝试 Deno with oak 并且我 运行 每次都遇到同样的错误 - 即使我尝试默认示例也是如此。我的工作环境是 macOs Big Sur。有人知道如何解决这个问题吗？

Found 6 errors.

示例代码来自此处 (https://github.com/oakserver/oak)，如下所示：

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

const app = new Application();

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

await app.listen({ port: 8000 });

谢谢！

错误是由于1.9之前的deno和v7之后的oak不兼容造成的

因为我几个小时前安装了 deno，所以我没有检查版本。使用自制软件我得到了一个旧版本 - 现在我使用

curl -fsSL https://deno.land/x/install/install.sh | sh 

相反。
