Running a modular Sinatra app on Heroku

#help

Hello, I'm having trouble getting a modular Sinatra app to run correctly in production. The git push heroku master works fine, but when I try to submit a form through the /contact page I get:

bundler: failed to load command: rackup (/app/vendor/bundle/ruby/2.4.0/bin/rackup).

My Procfile:

web: bundle exec rackup config.ru -p $PORT
Enter fullscreen mode Exit fullscreen mode

My config.ru:

require 'rubygems' require 'bundler' Bundler.require require_relative 'lib/app' run Tir::App
Enter fullscreen mode Exit fullscreen mode

My lib/app.rb:

require 'sinatra/base' require File.expand_path('articles', File.dirname(__FILE__)) require File.expand_path('static', File.dirname(__FILE__)) require File.expand_path('landing', File.dirname(__FILE__)) module Tir class App < Sinatra::Base #code end end
Enter fullscreen mode Exit fullscreen mode

I've tried all manner of tweaks but am stuck! Thanks for any help.

Hi Alex,

thanks for the reply. I'm assuming your example above is for a classic-style (not subclassed) Sinatra app? Mine is subclassed / modular, so I'm pretty much following the recipe outlined here: oreilly.com/library/view/sinatra-u...

I might give a classic-style version a try though, if only for debugging purposes. Cheers!
