Angular2 with Webpack: Cannot find module 'getstream'

Question

I have a really weird problem when building my angular2 solution with webpack (version 1.13.1).

When running the server I get an error saying:

Cannot find module 'getstream'

which is a module that I am using. The weird thing is that the module is working the way it should, and it is not required in any other place. The way I am requiring it is:

import stream = require('getstream');

Further more if I uninstall getstream using npm I get an other error, saying:

ERROR in ./src/main.ts
Module build failed: Error: Cannot resolve module 'getstream' in /Users/valdemarrolfsen/Utvikling/Applikasjoner/moj-web/src/lib/services

    at process._tickCallback (node.js:349:13)
 @ multi main

So the module is obviously found somehow. The module is also included in the package.json file of the project under devDependencies.

The reason why I need to fix this is that webpack allows me to run the application using:

npm run server

But if I try to build it using:

npm run build:prod

It crashes due to this error..

have you tried removing the ``node_modules`` folder and rerunning ``npm install``. Did you just misquote the way you import the getstream library or is the ``import`` statement used in that way something specific to angular? What happens when you try to require the getstream library from a node process in the same folder? — Matthisk, Jul 02 '16 at 09:36
After upgrading to angular rc4, and using the angular2-webpack-starter from AngularClass, the issue solved itself! — Valdemar Edvard Sandal Rolfsen, Aug 16 '16 at 12:04
All I did was to install get stream using npm install getstream And then importing it as shown above — Valdemar Edvard Sandal Rolfsen, Aug 16 '16 at 12:05
