"Ee: invalid module" error. The module tries to use observable's variable


#1

I am tying to use THREE.js lib and one of it’s sub-libs (GLTFExporter.js).

When I require GLTFExporter.js I got “Ee: invalid module” error.
Console throws the error (see screenshot).
Inside this module we have “THREE.GLTFExporter = function () {};”.
So the script tries to extend THREE.js module but cant see it.
THREE = require("three@0.99.0/build/three.min.js", "three@0.99.0/examples/js/exporters/GLTFExporter.js") doesnt work too.

When I copy the content of GLTFExporter.js to separate cell it woks well but this way is not convenient though.

Is there some workaround to require this module in usual way?
