按照示例代码

 <xr-ar-tracker mode="Marker" src="/static/ar/model.map">

      <xr-gltf model="gltf" anim-autoplay position="0.2 0 -0.2" scale="0.6 0.6 0.6" rotation="0 -50 0" />

    </xr-ar-tracker>

真机调试报错：

Error: not node js file system!path:/static/ar/model.map

 [xr-frame] Ar tracker process file error: copyFileSync:fail no such file or directory, copyFile "/static/ar/model.map" -> "wxfile://usr/xr-frame-ar-tracker-ar-tracker-1.map"

/static/ar/model.map 换成同位置jpg图片就没有任何问题，并可以完成2d marker效果
