I am trying to add ng-bootstrap to Angular2's quick start for TypeScript by following the instructions at https://ng-bootstrap.github.io/#/getting-started . When I do npm start it gives me the error TS2304 cannot find name 'NGB_PRECOMPILE'.
app.component.ts
import { Component } from '@angular/core';
import {NGB_DIRECTIVES} from '@ng-bootstrap/ng-bootstrap';
import { TasksComponent } from './tasks.component'
@Component({
selector: 'my-app',
directives: [ TasksComponent, NGB_DIRECTIVES ],
precompile: [ NGB_PRECOMPILE ],
template: `<h1 class="header">{{title}}</h1>
<tasks></tasks>`,
styles: [`
.header {
background: #999999;
border: 2px solid #444444;
}
`]
})
export class AppComponent {
title = 'To Do List - Alaska';
}
main.ts
import { bootstrap } from '@angular/platform-browser-dynamic';
import { AppComponent } from './app.component';
bootstrap(AppComponent);
and dependencies in package.son

The code I wrote follows the step-by-step instructions on the site: https://github.com/ng-bootstrap/ng-bootstrap . However, the section listed at the bottom shows what the component should look like as a whole and it lists both NGB_DIRECTIVES and NGB_PRECOMPILE in the import where the step-by-step instructions do not. This was my mistake of not having read the code entirely.
import {Component} from '@angular/core';
import {NGB_DIRECTIVES, NGB_PRECOMPILE} from '@ng-bootstrap/ng-bootstrap';
@Component({
selector: 'app',
directives: [ NGB_DIRECTIVES ],
precompile: [ NGB_PRECOMPILE ],
templateUrl: './app.html',
})
export class App {
...
}
This fixes the error TS2304 cannot find name 'NGB_PRECOMPILE'. However, I still cannot get bootstrap working in the application.
Did you add it to your systemjs.config.js
file?
//map tells the System loader where to look for things
var map = {
...
'@ng-bootstrap/ng-bootstrap': 'node_modules/@ng-bootstrap/ng-bootstrap'
};
//packages tells the System loader how to load when no filename and/or no extension
var packages = {
...
'@ng-bootstrap/ng-bootstrap': { defaultExtension: 'js', main: 'index.js' }
};
