typescript - 在 Google Colab 測試 Deno Jupyter 核心

我在使用 Google Colab 安裝/配置時遇到問題。

我的目標：在基於 Deno 的 Jupyter 筆記本核心中直接執行 Typescript。
我的問題：我是否如預期正確安裝了所有東西，或者是否還需要另一個庫，才能允許 Javascript/Typescript 在我更改運行時類型後直接在筆記本中運行？

要重現我的步驟：

前往 Google Colab 並打開一個新的筆記本：https://colab.google/ ，然後在各自的筆記本單元格中直接運行以下每個命令。
!pip 安裝 jupyterlab

Requirement already satisfied: jupyterlab in /usr/local/lib/python3.10/dist-packages (4.0.8)
Requirement already satisfied: async-lru>=1.0.0 in /usr/local/lib/python3.10/dist-packages (from jupyterlab) (2.0.4)
....

!curl -fsSL https://deno.land/x/install/install.sh | sudo DENO_INSTALL=/usr/local sh

如果我在一個單元格中運行以下代碼，它可以正常運行，但是

%%javascript
let x = 5;
let y = 2;
let z = x + y;
element.textContent = z

如預期的，JavaScript 不會直接在單元格內執行，除非我更改運行時。讓我們在下一步解決這個問題 :)

let x = 5;
let y = 2;
let z = x + y;
console.log(z);

File "<ipython-input-2-43a8c54cf62a>", line 1
    let x = 5;
        ^
SyntaxError: invalid syntax

它只是顯示：正在連接，但什麼也沒發生，接著出現以下彈出窗口：

await connected: disconnected

我感謝任何對這個問題的幫助。提前感謝！
