tns livesync ios error on before-watch hook

Hi I’m following the Building Apps with NativeScript and Angular 2 to build the groceries app. It works fine when I run tns run ios --emulator or tns livesync ios --emulator, but if I want to watch my files, doesn’t work at al… Is that any way to reload without watch?

I’m trying to run the follow command: tns livesync ios --emulator --watch

Here’s the error that happens on before-watch hook which is basically a require to the file nativescript-dev-typescript/lib/watch.js

I’ve runned a trace and the log is on pastebin. I post here the main errors:

The bug is with TypeScript, not NativeScript.

TypeScript has made some changes with case-sensitive and the solution @cmoffatt found it to Downgrade to TypeScript@1.7.5, you can read more here:
