"Cannot find module 'three' from"

I'm having a hard time migrating my toy typescript app at http://ssrb.github.io/mega-structure/mega-structure.html from typings to @types/npm.

The error I can't figure out is Error: Cannot find module 'three' and Error: Cannot find module 'codemirror'

The workflow is typescript/gulp/browserify.

For that migration, I deleted my typings.json as well as all the typing stuff from my gulpfile and npm install @types.

Then I fixed a few errors due to some API changes after upgrading the type definitions.

I replaced ///<reference path="typings/index.d.ts"/> with some import * as THREE from 'three';

It now fails to bundle and I'm trying to figure it out without success:

Solution

The problem was that the build was consuming type declarations forthree.js, codemirror, ... installed with npm but the matching javascript libraries were still installed using bower. After installing the libraries with npm rather than bower the build recovered.
