Add support for apt-based dependencies during both compile and runtime.
This buildpack is not meant to be used on its own, and instead should be in used in combination with Heroku's multiple buildpack support.
Include a list of apt package names to be installed in a file named
heroku buildpacks:add --index 1 https://github.com/heroku/heroku-buildpack-apt
source "https://rubygems.org" gem "pg"
$ heroku run bash -a apt-pg-test ~ $ irb irb(main):001:0> require "pg" => true irb(main):002:0> PG::version_string => "PG 0.15.1"
Copy the snippet above into CLI.
