Impossible de trouver le module "tslib"

Je vis ce problème et ne semble pas avoir de réponse à ce jour. Bien que je voie tslib dans mon dossier node_modules. Appréciez si quelqu'un peut aider à identifier ce qui ne va pas avec mon code. J'ai vu d'autres réponses à une question similaire, j'ai essayé de supprimer node_modules et de reconstruire l'ensemble du projet. Mais j'ai toujours le même problème

Uncaught Error: Cannot find module "tslib".

J'ai résolu le problème en supprimant la mauvaise importation pour le type. Cela devrait venir du noyau angulaire

enlevé

import { Type } from '@angular/compiler/src/core';

mis à jour

import { Injectable, Type } from '@angular/core';

Pour moi, le problème était la mauvaise version de TypeScript - j'avais 2.6.x. Sur un pressentiment, je suis passé à la dernière version 3.1.6, puis j'ai reçu ce message utile.

Le compilateur angulaire nécessite TypeScript> = 2.7.2 et <2.10.0 mais 3.1.6 a été trouvé à la place.

J'ai donc essayé la version 2.9.2 et le problème a été résolu.
