我正在尝试加载 ktx2 纹理，但出现此错误：
未捕获的语法错误：意外的标识符“html”（位于 是60c27b-a185-4e22-a763-bad0f7c717e0:6:11)
错误指向html标签：
/* constants */

我正在使用 webpack，并且加载纹理如下：
import {KTX2Loader} from 'three/addons/loaders/KTX2Loader.js';
import test from '../../../../assets/models/test.ktx2';
this.ktx2Loader = new KTX2Loader();
this.ktx2Loader.setTranscoderPath('../utils/decoders/basis');
this.ktx2Loader.detectSupport( this.renderer );
const texture = await this.ktx2Loader.loadAsync(test);
对 basic_transcoder 的 js 和 wasm 请求都返回 307 临时重定向。

在 Yuri Artiukh 视频上找到了解决方案，我只在本地处理此问题，但它解决了我的问题。
import * as THREE from "three"
import { REVISION } from "three"
const THREE_PATH = `https://unpkg.com/three@0.${REVISION}.x`
const ktx2Loader = new KTX2Loader()
ktx2Loader.setTranscoderPath(`${THREE_PATH}/examples/jsm/libs/basis/`)
ktx2Loader.detectSupport(this.renderer)
// after you have a mesh and its been added to the scene something like this should now work
ktx2Loader.load(tDiffuse, (texture) => {
material.uniforms.uDiffuse.value = texture
})
