    为了 use reveal.js in Deno Fresh ,我在岛上使用此代码:

    import { useEffect } from "https://esm.sh/v128/[email protected]/hooks/src/index.js";
    import Reveal from '../reveal/js/index.js';
    
    export default function Island() {
      useEffect(()=> {
          setDeck(new Reveal());
          deck.initialize();
      }) 
      return <>Text</>
    }
    

    我认为这是使用钩子的正确方法,但我得到了以下错误:

    An error occurred during route handling or page rendering.

      4 | export default function Island() {
    > 5 |   useEffect(()=> {
        |   ^
      6 |     newFunction();
      7 |
      8 |     function newFunction() {
    
    TypeError: Cannot read properties of null (reading '__hooks')

    会发生什么?

    您正在混合构建代码、生产代码和源代码( /hooks/src/... ),这是你不能做的。

    使用构建的挂钩输出: https://esm.sh/v128/ [email protected] /hooks
