Cannot import InMemoryDataService / Cannot install Rxjs

Ionic Framework ionic-v3

I’m installing angular-in-memory-web-api, npm output these errors:

ionic-hello-world@ /home/edxz/Documents/projects/ionic2

└── UNMET PEER DEPENDENCY rxjs@5.0.0-beta.12

When I tried to run:

$ npm i rxjs --save

it throws this error

I’ve tried running npm cache clear but its not solving this issue

I checked the node_modules folder, the angular-in-memory-web-api folder is there but I cannot find the InMemoryDbService class so I cannot import it.

what can I do to fix it? I need to use InMemoryDbService for my app while waiting for the backend to be finished.

Isn’t that intended for Angular1?

based on the description here, it is deprecated in favor of the angular repo: GitHub - angular/in-memory-web-api: The code for this project has moved to the angular/angular repo. This repo is now archived.

solved by running global update on all dependencies by using npm-check-updates module.
