Добрый день перевожу проект с Angular 4.3 на Angular 6 и возникла проблема с Observables.
Невозможно использовать пространство имен "Observable" как тип.
При попытке указать что должен вернуть метод, как это можно исправить ?
public postMethod(url: string, params: any, session: string = null): Observable<any> {
// do something
}
Использую эту
сборку, package.json следующий
