The Solution

Inside your project, you need to include the angular dependencies.

// make sure you have these items installed
    "typescript": "^2.0.6",
    "typings": "^1.5.0",

    "@angular/common": "~2.1.2",
    "@angular/compiler": "~2.1.2",
    "@angular/core": "~2.1.2",
    "@angular/forms": "~2.1.2",
    "@angular/http": "~2.1.2",
    "@angular/platform-browser": "~2.1.2",
    "@angular/platform-browser-dynamic": "~2.1.2",
    "@angular/router": "~3.1.2",
    "@angular/upgrade": "~2.1.2"

Also, check your node_modules to make sure there’s only one angular directory. It may be easier to delete your node directory and install typescript, typings, and angular2 using npm with the –save flag.
