If you want to run angular app ported from another machine without ng command then edit package.json as follows

"scripts": {
    "ng": "ng",
    "start": "node node_modules/.bin/ng serve",
    "build": "node node_modules/.bin/ng build",
    "test": "node node_modules/.bin/ng test",
    "lint": "node node_modules/.bin/ng lint",
    "e2e": "node node_modules/.bin/ng e2e"
  }

Finally run usual npm start command to start build server.
