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:
app/maint.ts
ap
It works for me:
In package.json dependencies block set ( use "angular" instead of "angular2")
"angular-in-memory-web-api": "^0.3.2",
Then run
npm install
OR
simply just run (my preferable)
npm install angular-in-memory-web-api --save
