error during installing Emscripten box2d

[michahell]

just an index.js file with:

var box2d = require('kripken/box2d.js');

gives me the error:

maybe / probably because that repo doesn't seem to cohere to any standard 📦 format ?

@michahell: you're right, it's not using any package format understood by duo. (ie: no component.json, no index.js, etc)

You can specify a JS path via: kripken/box2d.js:build/Box2D_v2.3.1_min.js (you may want to specify a git commit sha so the rug doesn't get pulled out from under you if they change versions or something)

Oh wow that is some awesome stuff, I expected there was a way to do something like that! my (ugly) workaround was to pull the three files that I needed into a /libs and then require those by hand, but that is even nicer! thanks!
