    format: 'cjs', main: 'bundles/ng2-bootstrap.umd.js', defaultExtension: 'js'
}

I am using the latest version of angular-cli 2.4.7 (webpack) and was able to get it to work.

Run this in your angular app

npm install ng2-bootstrap bootstrap moment --save

Open the following files and add them as listed

Insert a new entry into the styles array

  # angular-cli.json
  "styles": [
        "styles.css",
        "../node_modules/bootstrap/dist/css/bootstrap.min.css"
      ]

Import desired module

# src/app/app.module.ts
...
import { DatepickerModule } from 'ng2-bootstrap';
...
@NgModule({
....
,
  imports: [
DatepickerModule.forRoot(),
...
]
...})

And you are good to go!

This worked for me. Under the systemjs.config file:

map: {
'ng2-bootstrap': 'node_modules/ng2-bootstrap/bundles/ng2-bootstrap.umd.js',
       'moment': 'node_modules/moment/moment.js'
    }

We need to mention the 'moment' because ng2-bootstrap is importing moment.

And in the app.modules, just do the following:

import {DatepickerModule} from 'ng2-bootstrap';

And also the following:

@NgModule({
    imports: [
        ....,
        ....,
        DatepickerModule
    ],
    declarations: [...],
    providers: [...],
    bootstrap: [AppComponent]
})

                        **>-------- NG2BOOTSTRAP--------->**

Use these commands to add these dependencies to your package.json

  1. npm install moment --save
  2. npm install ng2-bootstrap --save

Modify your System.config.js to the following code as this map tells the System loader where to look for code.

var map = {
    'app':                        'app', // 'dist',
    '@angular':                   'node_modules/@angular',
     moment:              'node_modules/moment/moment.js',
    'ng2-bootstrap':              'node_modules/ng2-bootstrap',
  };

var packages = {
    'app':                        { main: 'main.js',    defaultExtension: 'js' },
    'ng2-bootstrap':          {defaultExtension: 'js' }
  };

Add Bootstrap to your index.html <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

App.module.ts import { Ng2BootstrapModule } from 'ng2-bootstrap/ng2-bootstrap'; And, add Ng2BootstrapModule to imports of @NgModule.

Then, U are good to go for ng2Bootstrap.

I had the same issue myself and found this link helpful: https://github.com/valor-software/ng2-bootstrap/issues/50#issuecomment-165448962

A snippet of the most relevant code:

System.JS config:

System.config({
   packages: {
     "app": {
        "defaultExtension": "js"
     },
     "node_modules/ng2-bootstrap": {
        "defaultExtension": "js"
     }
  },
  paths: {
    "ng2-bootstrap":   "node_modules/ng2-bootstrap"
  }
});

You can then simply import it like so:

import { Progressbar } from "ng2-bootstrap";
@Component({
    selector: "my-app",
    directives: [
        Progressbar
    ],
    template: "<progressbar></progressbar>" 
})

Hope this helps you, like it did to me.

I do not think the current answers are satisfactory since they do fighting symptoms and do not solve the underlying problem.

What I did to solve this:

System.config({
    baseURL: '/node_modules',
    "defaultJSExtensions": true,
    map: {
      app: '/app/'
    }
    paths: {
      "moment":   "moment/moment"
    }
  });

Line 1: So I set node_modules my base url, so I don't have to rewrite every import on a package by package basis.

Line 2: Then I tell systemjs to look for JS files by default.

Line 3 - 5: I map everything that starts with app to the app directory. So SystemJs won't try to find my own files in the /node_modules folder.

Finished.

On Line 6 - 7 One 'bugfix' had to be done when SystemJS tried to load momentjs directly from /node_modules/, so i set it to its own directory. Weird..
