ng build is broken: Could not resolve fs, net, os, crypto. But ng serve works (latest angular-cli).

Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

I am a first time Angular user

Description

The package "path" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

Minimal Reproduction

ng new myApp
cd myApp
npm install --save paper
import paper from 'paper';
console.log(paper);
npm start      // works OK - see the output in the console
npm run build // fails
