当运行代码时,我得到一个未处理的运行时错误,窗口未定义。网站运行正常,但构建失败。

下面是调用堆栈:

我已经把问题缩小到

extend({ThreeGlobe})


这导致了窗口错误。我想知道是否有一种方法可以使用钩子来扩展而不会导致窗口错误。

  • 编辑:我更改了代码以在开始时使用useEffect,但我得到了无效的钩子调用。
"use client";

import React, {useRef, useLayoutEffect, useEffect} from 'react';
import {Canvas, useFrame, extend, useThree} from "@react-three/fiber";
import countries from './globe-data-min.json';
import {Color, DirectionalLight, PointLight, NoToneMapping} from "three";
import Loading from "@/app/loading";

useEffect(()=> {
    const ThreeGlobe = () => import("three-globe")
}, [])

extend({ThreeGlobe})
...


编辑2:以下是我的尝试:1

const Globe = () => {
    const meshRef = useRef();

    useEffect(() => {
        import("@react-three/fiber").then(({ extend }) => {
            extend({ ThreeGlobe });
        });
    }, []);

    return (
        // ... (rest of the component code)
    );
};


这导致

Unhandled Runtime Error
Error: R3F: ThreeGlobe is not part of the THREE namespace! Did you forget to extend?

const Globe = () => {
    const meshRef = useRef();

    useEffect(() => {
        extend({ ThreeGlobe });
    }, []);

    return typeof window !== 'undefined' ? (
        <Canvas
            gl={{ antialias: true, toneMapping: NoToneMapping }}
            size={{ width: window.innerWidth, height: window.innerHeight }}
            resize={{ scroll: false }}
        >
            <ambientLight intensity={0.01} color={0xbbbbbb} />
            {/* ... (other lights and components) */}
            <GlobeObj />
        </Canvas>
    ) : null;
};


这仍然会导致窗口未定义
3

// changing ThreeGlobe import
const ThreeGlobe = React.lazy(() => import('three-globe'));
... 
//rest of the code is the same


我要

Target is not a constructor

cdmah0mi

cdmah0mi1#

你会得到这个错误,因为Next.js在构建过程中在服务器端呈现你的组件。该时间窗口对象不可用。
要修复此错误,需要在useEffect内部导入依赖于浏览器API的库

useEffect(()=>{
   const myLib = () => import(`path-to-my-lib`)
   ...
}, [])
