Update angular-cli to latest: npm install -g angular-cli@latest

And in my particular case, I updated the package.json to this:

"dependencies": {
    "@angular/common": "^2.4.0",
    "@angular/compiler": "^2.4.0",
    "@angular/core": "^2.4.0",
    "@angular/forms": "^2.4.0",
    "@angular/http": "^2.4.0",
    "@angular/platform-browser": "^2.4.0",
    "@angular/platform-browser-dynamic": "^2.4.0",
    "@angular/router": "~3.4.0",
    "core-js": "^2.4.1",
    "rxjs": "^5.0.1",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.7.2"
  },
  "devDependencies": {
    "@angular/compiler-cli": "^2.3.1",
    "@types/jasmine": "2.5.38",
    "@types/node": "^6.0.42",
    "angular-cli": "1.0.0-beta.24",
    "codelyzer": "~2.0.0-beta.1",
    "jasmine-core": "2.5.2",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "4.0.13",
    "ts-node": "1.2.1",
    "tslint": "^4.0.2",
    "typescript": "~2.0.3",
    "webdriver-manager": "10.2.5"
  }

Perform npm install with this package.json content and it'll work.
