Angular2 Tutorial (Tour of Heroes): Cannot find module 'angular2-in-memory-web-api'

Question

I have followed the Tutorial. After changing app/maint.ts in the Http chapter I get the error when starting the app via command line:

ap

Answer 1

For users who generated an empty project with angular cli 1.4.9 (Actual on October 2017) and then started follow the instructions step-by-step, just run the following command:

npm i angular-in-memory-web-api

Just that command, without anything additional.

Hope that saves someone's time
