Angular Bootstrapインストールエラー

Question

ngブートストラップをインストールしようとしていますが、エラーが発生しましたが、それはエラーと思われます。以下は、私がpackage.jsonファイルをインストールしたときに得られるメッセージです。

Answer 1

使用angular2（@angular）ライブラリの最新バージョン。エラーメッセージには、ng2-bootatrapが必要です。@ angle/core @〜2.4.0、@ angular/common @ 2.2.1など...

Answer 2

エラーはありません。ng-bootstrap依存関係として@angular/core@^2.3.1, @angular/common@^2.3.1 and @angular/forms@^2.3.1と表示され、バージョン2.4.0がインストールされています。 Npmはバージョン管理のためにsemverを使用します。したがって、^2.3.1 !== 2.4.0。
