@angular/core/index has no exported member 'Version'

After adding import { NgbModule } from '@ng-bootstrap/ng-bootstrap'; to my app I receive following error:

ERROR in [at-loader] node_modules@angular\forms\src\version.d.ts:13:10 Module ‘“…node_modules/@angular/core/index”’ has no exported member ‘Version’.

Angular: 2.1.0

ng-bootstrap: 1.0.0-alpha.16

Bootstrap: 4.0.0-alpha.5

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule } from '@angular/http';
import { AppComponent, Header, SearchBar } from './components/index';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';

@NgModule({
    imports: [ BrowserModule, HttpModule ],
    declarations: [ AppComponent, Header, SearchBar ],
    bootstrap:    [ AppComponent ]
})
export class AppModule {}

I would suspect that you are mixing up version of Angular modules (forms and core). In any case we are not importing any Version symbol(s) and can’t investigate / help without a minimal reproduction scenario using plunker or similar: https://github.com/ng-bootstrap/ng-bootstrap/blob/master/README.md#you-think-youve-found-a-bug

If you can demonstrate the issue in a plunker we can investigate, otherwise this issue is not actionable and will be closed.
