So i was using Rails 4.1 with Unicorn v4.8.2 and when i tried to deploy my app it doesn't start properly and into the unicorn.log file i found this error message:

  "app error: Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml` (RuntimeError)"

After a little research i found that Rails 4.1 change the way to manage the secret_key, so if we read the secrets.yml file located at exampleRailsProject/config/secrets.yml (you need to replace "exampleRailsProject" for your project name) you will find something like this:
  
  # Do not keep production secrets in the repository,
  # instead read values from the environment.
  production:
    secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

This runs a build for a small elixir (phoenix) project in about 40 seconds by caching as much of the compiled files as possible.

We've been using this for months in multiple projects without any issues. Please ping be if there is any issues with this script and I'll update it.

It should be generic enough to work on any elixir app using mix.

If you have a elixir_buildpack.config, then enable that section in the build script to keep versions in sync!

2016-08-09: Updated to newer Erlang and Elixir and fixed curl command.

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
