three。js报错TypeError: Cannot read properties of undefined (reading 'SphereGeometry')

在Three.js中，当出现“TypeError: Cannot read properties of undefined (reading 'SphereGeometry')”这样的错误时，通常是因为没有正确导入所需的Three.js库或模块。请确保已正确导入所需的Three.js库或模块，并检查代码中是否存在拼写错误或语法错误。

以下是一个创建球体的Three.js示例代码，可以作为参考：

import * as THREE from 'three';

const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

const geometry = new THREE.SphereGeometry(5, 32, 32);
const material = new THREE.MeshBasicMaterial({ color: 0xffff00 });
const sphere = new THREE.Mesh(geometry, material);
scene.add(sphere);

camera.position.z = 10;

function animate() {
  requestAnimationFrame(animate);
  sphere.rotation.x += 0.01;
  sphere.rotation.y += 0.01;
  renderer.render(scene, camera);
}
animate();
