Desired functionality.

should serve the demo app

Mention any other details that might be useful.

webpack is duplicated.. because angular cli has a dependency to webpack too...

SOLVED:

1. cd demo
2. npm rm webpack
3. rm -rf node_modules package-lock.json
4. npm i
5. ng serve

🎉 and it works

so you should remove webpack from the package.json from the demo directory

thank you

I agree the dependency may be redundant with cli's, but still, it shouldn't cause this error... (i tried installing demo deps with yarn and it worked fine, no error on gulp serve:demo...)

Anyway, i removed it
