Had the same issue when trying to build a project from scratch that built without error _yesterday_…

Managed to fix this by explicitly pinning down dependencies to the versions I had in a working copy:

    "serve:before": "watch",
    "emulate:before": "build",
    "deploy:before": "build",
    "build:before": "build",
    "run:before": "build"
  },
  "dependencies": {
    "@angular/common": "2.1.0",
    "@angular/compiler": "2.1.0",
    "@angular/compiler-cli": "0.6.2",
