I am trying to migrate an Angular JavaScript (ES5) project to TypeScript 2.0 step by step and must admit I'm very struggling.
So first I changed the index.js to index.ts and used the recommended method of installing typings (npm install --save @types/node) instead of the old typings.json way.

Build setup uses gulp with browserify and now introducing tsify and babelify as suggested here.

browserify

//... .plugin(tsify) .transform(babelify, { presets: ['es2015'], extensions: ['.ts', '.js'] }) //... 

tsconfig.json

{ "files": [ "assets/app/index.ts" ], "compilerOptions": { "target": "es5", "module": "commonjs", "moduleResolution": "node", "sourceMap": true, "emitDecoratorMetadata": true, "experimentalDecorators": true, "removeComments": false, "noImplicitAny": false } } 

However the build fails with:

TypeScript error: .tmp/public/app/index.ts(4,15): Error TS2304: Cannot find name 'require'.

tsify seems not to copy the installed typings to the output dir, which causes the above error.
Any suggestion on how to solve the problem?

EDIT
Copying the node_modules/@types folder to the root of my C: drive eliminates the error, but I have no idea why...
