angular-tour-of-heroes giving me issues

[SidX]

I was using the https://angular.io/docs/ts/latest/tutorial/

and the underlying  pakage i was using was https://angular.io/docs/ts/latest/quickstart.html

I have absolutely made any changes except the name of the root folder and package name in package.json from "angular2-quickstart"  to "angular-tour-of-heroes"

However when i have put npm start i am getting the following error

0 info it worked if it ends with ok

18 error This is most likely a problem with the angular-tour-of-heroes package,

18 error not with npm itself.

18 error Tell the author that this fails on your system:

18 error     tsc && concurrently "tsc -w" "lite-server"

18 error You can get information on how to open an issue for this project with:

18 error     npm bugs angular-tour-of-heroes

18 error Or if that isn't available, you can get their info via:

18 error

18 error     npm owner ls angular-tour-of-heroes

18 error There is likely additional logging output above.

19 verbose exit [ 1, true ]
