You must first import `GLTFLoader` from a separate file (it’s not a part of core ThreeJS.)  
See this example:

> <https://github.com/mrdoob/three.js/blob/79edf22a345079dc6cf5d8c6ad38ee22e9edab3c/examples/webgl_loader_gltf.html#L23>

Edit: The error suggests your code looks a bit different, too. It should be `new GLTFLoader()`, without the `THREE.` part.
