Heroku app does not start (No such file or directory /usr/bin/env: ruby), Ubuntu

Question

I'm aiming to implement a Scrivito test app and deploy it to Heroku. I am able to push to Heroku successfully, but when I open the Heroku app, I receive the following error in my Heroku logs.

"usr/bin/env ruby" is found in four files in my app:

C:\Users\Laura\Documents\railsVM\scrivito_example_app\bin\bundle:
   1: #!/usr/bin/env ruby
   2  ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)
   3  load Gem.bin_path('bundler', 'bundle')

C:\Users\Laura\Documents\railsVM\scrivito_example_app\bin\rails:
   1: #!/usr/bin/env ruby
   2  APP_PATH = File.expand_path('../../config/application', __FILE__)
   3  require_relative '../config/boot'

C:\Users\Laura\Documents\railsVM\scrivito_example_app\bin\rake:
   1: #!/usr/bin/env ruby
   2  require_relative '../config/boot'
   3  require 'rake'

C:\Users\Laura\Documents\railsVM\scrivito_example_app\bin\setup:
   1: #!/usr/bin/env ruby
   2  require 'pathname'

My Gemfile:

source 'https://rubygems.org'
ruby "2.3.0"

gem 'autoprefixer-rails'
gem 'bootstrap-sass'
gem 'dotenv-rails'
gem 'jbuilder', '~> 2.0'
gem 'jquery-rails'
gem 'rails', '4.2.6'
gem 'sass-rails', '~> 5.0'
gem 'scrivito', '1.5.1'
gem 'scrivito_advanced_editors'
gem 'secure_headers'
gem 'uglifier', '>= 1.3.0'

group :development do
  gem 'web-console'
  gem 'listen', '~> 3.0.5'
end

group :production do
  gem 'pg'
  gem 'rails_12factor'
end`

I am on Windows 10 running Ubuntu 14.04.

I am wondering if this has to do with the fact that I recently updated to Rails 5, but Scrivito does not yet support it. I've pushed to Heroku both with and without a Ruby version specified, thinking that was the issue. None of the other questions on this topic seem to resolve my issue.

UPDATE: I've pushed an updated Gemfile to Heroku now which includes Ruby 2.3.1. When I run heroku run "ruby -v" I receive the results: ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]. Error is still occurring in Heroku. — lltheis

I found out the issue with all this was that on my Windows / Vagrant environment, the line breaks in the bin folder were mixed up. I ran rake rails:update:bin and pushed the changes through and all's well to run it on Heroku!
