I'm Getting this error TypeError: undefined is not a function (near '...AFRAME.registerComponent...') when I try this code:

I don't know if I do something wrong.

<a-scene>
    <ar-geopose id="WRK" lla="20.6247719 -87.0828196" userotation="false">
        <a-box  rotation="0 45 0" width="1" height="1" depth="1"  color="#4CC3D9"></a-box>
    </ar-geopose>
</a-scene>
