Error in Heroku "failed to compile Multipack app"

It's only been half a year since I started studying programming. I am thinking of deploying Heroku+Rails+Grunt.

The other day you told me about this article (http://qiita.com/icb54615/items/e5d4db164c5002e4b183).

$git push heroku master

----- > Fetching custom git buildpack ... done
----- > Multipack app detected
=====>Downloading Buildpack: https://github.com/getgamba/heroku-buildpack-nodejs-grunt-compass.git

 !     Push rejected, failed to compile Multipack app

The error appears.

I would appreciate your advice.

Thank you for your cooperation.

I had the same error, but it has been resolved, so I will share it with you.

https://github.com/getgamba/heroku-buildpack-nodejs-grunt-compass/blob/master/bin/detect
If you look at the nodejs buildpack code above, the nodejs app detects the directory named client.Therefore, I think it will be fixed if you change the name of the directory where the front-end application is placed from front to client.

Additional information

Heroku's multi-buildpack appears to be officially supported https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app
You may want to use this method.
Also, package.json will not be installed when you deploy unless you write dependencies on dependencies as well as devDependencies.
