Import component from a different repo

问题

I created a repo in bitbucket which called "angular-lister", the structure of the repo is:

Then I created another repo which have the same structure (sort of, cant put picture here and it doesnt really matter).
In this second repo I installed my repo using npm i --save path/to/angular-lister.git and I saw it was added to my package json + it's located under my node_modules folder.

I am trying to import a component from angular-lister (app/app.component) but I am unable to do it.

This is my app.module.ts of the second repo (NOT angular-lister):

import { ListerAppComponent } from 'node_modules/angular-lister/app/app.component'

@NgModule({
    imports:      [
        ...
    ],
    declarations: [
        ...,
        ListerAppComponent
    ],
    bootstrap:    [ ...]
})

and I get the following error:

zone.js:1382 GET http://localhost:3000/node_modules/angular-lister/app/app.component 404 (Not Found)

Why is that, what am I doing wrong here?

node_modules/agnular-lister:

回答1:

node_modules should not be there since you are already telling SystemJS to check in that folder. Just edit it by this:

import { ListerAppComponent } from './angular-lister/app/app.component'

Keep in mind that you can't just import the project, you have to create a npm package and export the right thing. this tutorial is a good entrypoint to understand how it works.
