Why in Angular 2, ErrorHandler module doesn't exist?

Question

When I import the "ErrorHandler" module like this:

import { NgModule, ErrorHandler } from '@angular/core';

Visual studio indicates "Module .../@angular/core/index has no exported member 'ErrorHandler'"

Why ? It isn't installed ? how to install it ?

Thx!

thx but it doesn't work... I tried to update package.json "2.0.0-rc.5" -> "^2.3.1" and again "npm install @angular/core" but it doesn't work either

try making it "@angular/core": "~2.1.2"

@amorel It happens with the libraries.... u need the version of code in sync with the libraries....
