Déploiement vers heroku - échec de la détection du buildpack nodejs (jasonswett)

Question

Je suis le tutoriel du livre "Angular for Rails Developers" de Jason Swett. Le sujet se trouve au chapitre 2 : Deployment.

J'ai d'abord fait ça :

$ rm -rf public
$ ln -s client/dist public

Puis après avoir créé l'application dans heroku, j'ai ajouté les buildpacks

$ heroku buildpacks:add https://github.com/jasonswett/heroku-buildpack-nodejs
$ heroku buildpacks:add heroku/ruby

Voici les résultats des builpacks

=== author-wizard Buildpack URLs
1. https://github.com/jasonswett/heroku-buildpack-nodejs
2. heroku/ruby

Voici le fichier package.json

{
      "name": "author-wizard",
      "version": "0.0.0",
      "license": "MIT",
      "angular-cli": {},

        "start": "ng server",
        "postinstall": "typings install && ng build",
        "lint": "tslint \"src/**/*.ts\"",
        "format": "clang-format -i -style=file --glob=src/**/*.ts",
        "pree2e": "webdriver-manager update",
        "e2e": "protractor"
      },
      "private": true,
      "dependencies": {
        "@angular/common": "2.0.0-rc.1",

        "zone.js": "^0.6.12",
        "angular-cli": "0.0.*",
        "clang-format": "^1.0.35",
        "codelyzer": "0.0.14",
        "ember-cli-inject-live-reload": "^1.4.0",
        "jasmine-core": "^2.4.1",
        "jasmine-spec-reporter": "^2.4.0",

        "karma-chrome-launcher": "^0.2.3",
        "karma-jasmine": "^0.3.8",
        "protractor": "^3.3.0",
        "ts-node": "^0.5.5",
        "tslint": "^3.6.0",
        "typescript": "^1.8.10",
        "typings": "^0.8.1"
      },
      "devDependencies": {

      }
    }

Quand j'ai poussé vers heroku :

$ gp heroku master

J'apprécierais toute aide. Merci.

Mise à jour :

J'ai lancé le git push dans les rails Root. Voici la sortie de ls -la ; ls -la client :
