https://github.com/angular/quickstartのangle2-seedを使用しています。自分のクラスの単体テストをしたい。以下は私のテストで：カルマ：XHRエラー（404が見つかりません）ロードsrc/node_modules/angular2-jwt/angular2-jwt.js
describe('my method',() => {
it('should expect true',() => {
mockContextSettings = jasmine.createSpyObj('mockContextSettings', ['environment']);
mockWindow = jasmine.createSpyObj('mockWindow', ['location']);
workContext = new WorkContext(mockContextSettings, mockWindow);
expect(true).toBe(true);
});
});
テストは
workContext = new WorkContext(mockContextSettings, mockWindow);
なくても正常に動作します。しかし、私は私のテストでそれを持っているとき、私はカルマのブラウザコンソールで次のエラーが表示されます。
GET http://localhost:9876/base/src/node_modules/angular2-jwt/angular2-jwt.js 404 (Not Found)

私は私のパッケージでangular2-JWTを持っています.jsonの依存関係を確認してインストールしてください。私は本当に問題が何であるか分からない。
UPDATE：
が再びテストを実行し、理由もなく、この時間は、それがangular2-jwt.jsをロードします！しかし、まだ別の問題：このファイルは行があります（「...」）が必要ですので、私はカルマブラウザのコンソールで次のエラーにこの時間を取得：
Uncaught ReferenceError: require is not defined
at node_modules/angular2-jwt/angular2-jwt.js:19
うわー！問題を修正しました。驚くばかり！私はこの間何日も挫折しました！どうもありがとう！心から感謝する！ – hosjay
あなたは確かに歓迎です。それがあなたのために働いてうれしい。 –
