Running both Bundler and NPM on Heroku

Question

I have a Node.js app that uses Compass, a Ruby gem.

When I push to Heroku it will detect a Node.js app and run npm install . Now, it detects the Gemfile first which it a ruby project and no longer runs npm install . Is it possible to tell Heroku this is a Node.js app which requires the Gemfile for running bundle exec install compass ?

Answer 1

You need to use a custom buildpack that supports both Ruby and Node. Take a look at third-party buildpacks and multi buildpacks .
