Three.js只是在画一个白色的屏幕

我正在尝试遵循以下教程：https://threejs.org/docs/#manual/en/introduction/Creating-一个场景，我的浏览器只显示了一个白色窗口。我试着把这些文件分成js和html两个文件。

我已经尝试过的：

添加/删除脚本标记中的nomodule参数
运行本地实时服务器

这是我的代码：

我的index.html文件

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>My first three.js app</title>
<style>
body { margin: 0; }
</style>
</head>
<body>
<script nomodule src="js/main.js"></script>
<script>
// Our Javascript will go here.
</script>
</body>
</html>

我的js文件名为main.js，位于文件夹"js"中。我通过npm安装了Three.js。

import * as THREE from 'three'
//import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
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();
const material = new THREE.MeshBasicMaterial({color:0x00ff00});
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);
camera.position.z = 5;
const animate = function () {
requestAnimationFrame(animate);
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render(scene, camera);
};
animate();

相反的示例代码：

<!DOCTYPE html>
<html>
<head>
<title>My first three.js app</title>
<style>
body { margin: 0; }
</style>
</head>
<body>
<script src="js/three.js"></script>
<script>
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();
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const cube = new THREE.Mesh( geometry, material );
scene.add( cube );
camera.position.z = 5;
const animate = function () {
requestAnimationFrame( animate );
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render( scene, camera );
};
animate();
</script>
</body>
</html>

这将呈现一个绿色旋转立方体：

<!DOCTYPE html>
<html>
<head>
<title>My first three.js app</title>
<style>
body { margin: 0; }
</style>
</head>
<body>
<script type="module">
import * as THREE from 'https://unpkg.com/three/build/three.module.js';
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();
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const cube = new THREE.Mesh( geometry, material );
scene.add( cube );
camera.position.z = 5;
const animate = function () {
requestAnimationFrame( animate );
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render( scene, camera );
};
animate();
</script>
</body>
</html>

您需要包含"three.js"；在js/文件夹中。

"在我们开始"；章节：https://threejs.org/docs/#manual/en/introduction/Creating-a-新烯

"将以下HTML与js/目录中的three.js的副本一起保存到计算机上的文件中，然后在浏览器中打开">

将browsersList添加到package.json对我有效。

"browserslist": [
"last 1 Chrome version"
]
