所以到目前为止，我一直在使用 three.js 和 webXR 一段时间，并希望将其集成到汇编脚本中。我知道如何让 webXR 在 typescript 中工作，但是当我尝试在汇编脚本中使用它时，它会在导入时出错。这是 index.ts 代码和错误：

索引.ts：

// The entry file of your WebAssembly module.
import type { Navigator } from 'webxr';

export function add(a: i32, b: i32): i32 {
    return a + b;
}

错误：

ERROR TS1005: 'from' expected.

import type { Navigator } from 'webxr';

Assemblyscript 编译为 Web Assembly，此时它无法访问 DOM。这个想法是使用 Assemblyscript 作为游戏逻辑，使用常规 javascript / typescript 与 WebXR API 交互。
