Ionic: Error: Module build failed: Error: ENOENT: no such file or directory

I am using Ionic, and get the following error:

Runtime Error Uncaught (in promise): Error: Module build failed: Error: ENOENT: no such file or directory, open '/Users/richardmarais/Development/ionic/theWhoZoo/src/pages/model/ratingModel.js'

The error is a result of this line of code:

this.ratingModel = new RatingModel();

When I remove this line, I don't get the error.

ratingModel.ts

import { Injectable } from "@angular/core";
import { PersonModel } from './personModel';
import { JobModel } from './jobModel';

@Injectable()
export class RatingModel {
        public id: number = null;
        public job: JobModel = null;
        public review: string = null;
        public rating: number = null;
        public reviewDate: number = null;
        public time: string = null;
        public person: PersonModel = null;
        public anonymous: number = null;

        constructor() {

        }
}

Reading other forums, people are getting this error due to the case not matching in their imports, but I have checked mine, and they do match.

import { RatingModel } from '../model/ratingModel';

However, I have noticed something strange in my IDE (Visual Studio Code):

As you can see, in the search results, there are two files for the object, ratingModel.ts and RatingModel.ts. But when I check the actual files system, there is only on file, ratingModel.ts:

Question

Does anyone know what and how to resolve what looks like possibly a bug or fault here?

Thanks
