我开始学习 Angular2，我想在我的项目中使用 ng-bootstrap。但是，我无法制作一个工作项目。导入 ng-bootstrap 失败。由于我是初学者，我不知道问题是因为代码还是我犯的其他错误。
您能否为我提供一个使用 ng-bootstrap 和 Angular2 的工作且简单的项目，以便我可以尝试使其在我的计算机上运行？
编辑：
app.module.ts：
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
import { AppComponent } from './app.component';
import { NgbdAlertCloseable } from './ngbd-alert-closeable.component';
@NgModule({
imports: [ NgbModule, BrowserModule ],
declarations: [ NgbdAlertCloseable, AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
systemjs.config.js：
/**
* System configuration for Angular 2 samples
* Adjust as necessary for your application needs.
*/
(function(global) {
// map tells the System loader where to look for things
var map = {
'app': 'app', // 'dist',
'@angular': 'node_modules/@angular',
'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
'rxjs': 'node_modules/rxjs',
'@ng-bootstrap': 'node_modules/@ng-bootstrap'
};
// 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' },
'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
'ng-bootstrap': { main: 'index.js', defaultExtension: 'js' }
};
var ngPackageNames = [
'common',
'compiler',
'core',
'forms',
'http',
'platform-browser',
'platform-browser-dynamic',
'router',
'router-deprecated',
'upgrade',
];
var ngBootstrapPackageNames = [
'accordion',
'alert',
'bundles',
'buttons',
'carousel',
'collapse',
'dropdown',
'esm',
'modal',
'pagination',
'popover',
'progressbar',
'rating',
'tabset',
'timepicker',
'tooltip',
'typeahead',
'util'
];
// Individual files (~300 requests):
function packIndex(pkgName) {
packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
}
// Bundled (~40 requests):
function packUmd(pkgName) {
packages['@angular/'+pkgName] = { main: 'bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
}
function ngBootstrapPackIndex(pkgName) {
packages['@ng-bootstrap/ng-bootstrap/' + pkgName] = {main: 'index.js', defaultExtension: 'js'};
}
ngBootstrapPackageNames.forEach(ngBootstrapPackIndex);
// Most environments should use UMD; some (Karma) need the individual index files
var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
// Add package entries for angular packages
ngPackageNames.forEach(setPackageConfig);
var config = {
map: map,
packages: packages
};
System.config(config);
})(this);
错误：
