Error: XHR error (404 Not Found) loading http://localhost:8080/node_modules/ng2-bootstrap/ng2-bootstrap.js(…)

this is my index.html:

</script>
</head>

</html>

here is systemjs.config.js:

(function (global) {

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

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

var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/router-deprecated',
    '@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's chance to modify config before we register it.
if (global.filterSystemConfig) {
    global.filterSystemConfig(config);
}

System.config(config);

})(this);

here is part of app.component.ts:

//datepicker
import {DATEPICKER_DIRECTIVES} from 'ng2-bootstrap/ng2-bootstrap';
