Library only works as a standalone - mocha cannot be bundled with webpack

[devhazem]

When using it in an Angular 2 project, I get the following error (even though the file does exist):
Error: Webpack Compilation Error C:/app/node_modules/mocha/lib/browser/growl.js Module not found: Error: Can't resolve '../../package' in 'C:\app\node_modules\mocha\lib\browser' resolve '../../package' in 'C:\app\node_modules\mocha\lib\browser' using description file: C:\app\node_modules\mocha\package.json (relative path: ./lib/browser) using description file: C:\app\node_modules\mocha\package.json (relative path: ./package)

I have opened a mocha issue. Do you have any idea how to make this work?
