Why is my middleman heroku app ignoring the Procfile?

Question

I've been struggling trying to launch my middleman repo to heroku. I've followed a tutorial http://randomerrata.com/post/56163474367/middleman-on-heroku, but have had continued issues. Although installing the puma gem, for some reason the procfile is being ignored and the heroku app keeps pointing to web bundle exec sudo unicorn_rails -c ./config/unicorn.rb -p $PORT -D --env production

Any idea how to get this thing to stop pointing to the unicorn rails and use puma?

Answer 1

Perhaps it would be worth checking out middleman-heroku as a different route to take. Alternatively I would check that your Gemfile.lock is up to date and committed.

Answer 2

I would try tailing the logs with heroku logs -t to see if you can see what's happening.

Is your Procfile called Procfile with a capital P?

What does it look like, can you post it here?

My Procfile has web: bundle exec puma -p $PORT. Is Puma listed in your Gemfile?
