Specyficzna wersja npm na Heroku

Question

Próbuję wypchnąć moją aplikację internetową na Heroku, jednak wymaga to konkretnej wersji NPM (> 2.0, a mianowicie dlatego, że chcę zainstalować moduły z local paths).

Próbowałem określa wersję npm chcę w moim pliku package.json tak:

"engines": { 
    "node": "0.10.x", 
    "npm": "2.1.6" 
    }, 

Ale to nie działa. Otrzymuję:

Mailgun to moduł, który chcę zainstalować z lokalnej ścieżki. Jak widać, wersja npm nadal 1.4.28.

Każdy pomysł na wymuszenie określonej wersji NPM na Heroku?

Dzięki!

Jeśli potrzebujesz konkretnej wersji NPM, która nie jest domyślnie dostępna na Heroku, będziesz musiał build a custom buildpack.
