问题
Just to clarify this: I'm completely new to AngularJS and to any Web Technology. I'm a beginner when it comes to Web Development.
I tried to install it and I've gotta admit, after many "Unknown Buttons Pressings", I may have done a big mess, or maybe not.
I followed AngularJS Website's Tutorial to install Angular and then I just wanted to push the "Red Button":
npm start
But it threw an error saying:

24 error If you do, this is most likely a problem with the apanpie package,
24 error not with npm itself.
24 error Tell the author that this fails on your system:
24 error ng serve
24 error You can get information on how to open an issue for this project with:
24 error npm bugs apanpie
24 error Or if that isn't available, you can get their info via:
24 error npm owner ls apanpie
24 error There is likely additional logging output above.
25 verbose exit [ 1, true ]
So I've searched all around the Google Globe, but found nothing.
Also, I don't know if this is related, but in my TypeScript code:
import { View, Component } from '@angular2/core';
[... Components Here ... ]
it throws an error:
Cannot find module '@angular2/core'
If anyone could enlighten me, that would make me so happy!

its a bit weird, but the root folder should be named like in this pattern, my-app, tour-of-heroes.
earlier today i had this problem, wrongly copied my-app like this: sudo cp -rv my-app tourOfHeroes then ran npm start inside tourOfHeroes got that error
then after a few hours decided to do: sudo cp -rv my-app tour-of-heroes then ran npm start inside tour-of-heroes then like magic it ran and im back in business
