System js map doesn't work

问题:

Maybe I am dumb but system js always gives so much pain, although its so nice that I don't want to use anything else.

My system js config is this:

System.config({
        packages: {
            app: {
                format: 'register',
                defaultExtension: 'js'
            },
            primeng:{
                format: 'register',
                defaultExtension: 'js'
            }
        },
        map: {
          primeng: 'node_modules/primeng'
        }
    });

Primeng is being imported like this:

import {Accordion} from "primeng/primeng";
import {AccordionTab} from "primeng/primeng";

This is a ts file which gets compiled in js by gulp and then used by my index.html.

But in my terminal I get error:

error TS2307: Cannot find module 'primeng/primeng'

If anyone has any idea, please solve this

Figured it out.

We have to reference the type definition in the component's .ts file itself. So at the top of my component file I have to write this:

///<reference path="../../node_modules/primeng/components/accordion/accordion.d.ts"/>
