THREE加载glb模型

报错： THREE.GLTFLoader: No DRACOLoader instance provided

import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader'

import { DRACOLoader } from 'three/examples/jsm/loaders/DRACOLoader'

return new Promise((resolve, reject) => {
      const loader = new GLTFLoader()
      const dracoLoader = new DRACOLoader()
      dracoLoader.setDecoderPath('/static/draco/')
      loader.setDRACOLoader(dracoLoader)
      loader.load(gltfPath, function (obj) {
        resolve(obj)
      })
    })
  }

使用DRACOLoader  加载
