Это код:

systemjs.config.js:

(function(global) {

    // map tells the System loader where to look for things
    var map = {
        'app':                        'app', // 'dist',
        'rxjs':                       'node_modules/rxjs',
        '@angular':                   'node_modules/@angular',
        'ng2-dragula':                'node_modules/ng2-dragula', //for ng2-dragula
        'dragula':                    'node_modules/ng2-dragula' //for ng2-dragula
    };

    // packages tells the System loader how to load when no filename and/or no extension
    var packages = {
        'app':                        { main: 'boot.js',  defaultExtension: 'js' },
        'rxjs':                       { defaultExtension: 'js' },
        'ng2-dragula': { main: 'ng2-dragula.js', defaultExtension: 'js' } //for ng2-dragula
    };

    var packageNames = [
        '@angular/common',
        '@angular/compiler',
        '@angular/core',
        '@angular/http',
        '@angular/platform-browser',
        '@angular/platform-browser-dynamic',
        '@angular/router',
        '@angular/testing',
        '@angular/upgrade'
    ];

    // add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
    packageNames.forEach(function(pkgName) {
        packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
    });

    var config = {
        map: map,
        packages: packages
    };

    // filterSystemConfig - index.html chance to modify config before we register it.
    if (global.filterSystemConfig) { global.filterSystemConfig(config); }

    System.config(config);

})(this);

app.component.ts:

import {Component} from '@angular/core';
import {Dragula, DragulaService} from 'ng2-dragula/ng2-dragula';

@Component({
    selector: 'my-app',
    directives: [Dragula],
    viewProviders: [DragulaService],
    template:'
  <div>
    <div class='wrapper'>
      <div class='container' [dragula]='"first-bag"' style="background-color:green;padding:10px;margin-bottom:20px;">
        <div>You can move these elements between these two containers</div>
        <div>Moving them anywhere else isn't quite possible</div>
        <div>There also the possibility of moving elements around in the same container, changing their position</div>
      </div>
      <div class='container' [dragula]='"first-bag"' style="background-color:red;padding:10px;margin-bottom:20px;">
        <div>This is the default use case. You only need to specify the containers you want to use</div>
        <div>More interactive use cases lie ahead</div>
        <div>Make sure to check out the <a href='https://github.com/bevacqua/dragula#readme'>documentation on GitHub!</a></div>
      </div>
    </div>
  </div>
  ',
})
export class AppComponent {

}

Если вы попытаетесь перетащить divs, ничего не произойдет.

Что я здесь пропустил или сделал не так?

    Любые ошибки в консоли браузера?

    Да, я добавил это к вопросу выше. Это не останавливает работу приложения, но если вы посмотрите на консоль, это ошибки

Попробуй это:

systemjs.config:

var map =       {
    ...
    'dragula': 'node_modules/dragula/dist/dragula.js',
    'ng2-dragula': 'node_modules/ng2-dragula'
  };

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

var config = {
    map: map,
    packages: packages  
  }'

Затем импорт

import {Dragula, DragulaService} from 'ng2-dragula/ng2-dragula';

И в @Component

directives: [Dragula], 
viewProviders: [DragulaService]

На вашей карте, как dragula, так и ng2-dragula указывают на то же место.

'ng2-dragula':                'node_modules/ng2-dragula', //for ng2-dragula
'dragula':                    'node_modules/ng2-dragula' //for ng2-dragula

Я думаю, что это должно быть -

            'dragula': 'node_modules/dragula/dist/dragula.js',
            'ng2-dragula/*': 'node_modules/ng2-dragula/ng2-dragula.js',

Посмотрите, поможет ли это.
