heroku-buildpack-hiredis

If a gem is depending on hiredis during gem install (such as recommendify), git push heroku master fails since Heroku slug compiler doesn't have hiredis by default. In this case, you need to add hiredis first and setup proper PATHs before you run bundle install. This buildpack is in charge of doing it.

How to use

Specify buildpack

heroku config:add BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

Add .buildpacks

cat << EOF > .buildpacks
