我想学习 three.js 并尝试按照 three.js 文档中的入门代码进行操作，但场景没有渲染，我完全不知所措。

主程序：
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.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const cube = new THREE.Mesh( geometry, material );
scene.add( cube );
camera.position.z = 5;
function animate() {
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render( scene, camera );
}
renderer.setAnimationLoop( animate );
我不知道哪里出了问题，但唯一显示的是标题。请帮忙！
您在导入地图时语法有误。这不是我们标记库版本的方式。我们没有将版本号（ 可能有点令人困惑，因为它们在文档中呈现了它…… ）括在尖括号中 <> 。像这样就可以了： v0.167.1 或者 0.167.1 但 不能 像这样： <v0.167.1> .

尝试这种方法：
<script type="importmap">
{
"imports": {
"three": "https://cdn.jsdelivr.net/npm/[email protected]/build/three.module.js",
"three/addons/": "https://cdn.jsdelivr.net/npm/[email protected]/examples/jsm/"
}
}

<script type="module">
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.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const cube = new THREE.Mesh( geometry, material );
scene.add( cube );
camera.position.z = 5;
function animate() {
