I created my rails with this template that included webpack. But i still wrote my javascript code in app/assets/javascript. Now I am trying to deploy my app to heroku and it keeps failing. I get this error

remote: /tmp/build_6f0656280cbbda40c5832ccb79fc1783/vendor/bundle/ruby/2.3.0/gems/bundler-1.15.2/lib/bundler/rubygems_integration.rb:432:in `block in replace_bin_path': can't find executable webpack for gem webpacker (Gem::Exception)

The main error seems to be "cant find executable webpack for gem webpacker". I have no idea how to solve it. This is my gemfile 

source 'https://rubygems.org'
ruby '2.3.5'

gem 'figaro'
gem 'jbuilder', '~> 2.0'
gem 'puma'
gem 'rails', '5.1.4'
gem 'redis'
gem 'cloudinary'
gem 'carrierwave', '~> 1.2'
gem 'rails_admin', '~> 1.2'
group :production do
 gem 'pg', '~> 0.20'
end



gem 'autoprefixer-rails'
gem 'bootstrap-sass'
gem 'jquery-rails'
gem 'font-awesome-sass'
gem 'sass-rails'
gem 'simple_form'
gem 'turbolinks', '~> 5.0.0'
gem 'coffee-rails'

gem 'uglifier'
gem 'webpacker'
gem 'devise'
gem 'ransack'
gem 'trix'


gem "letter_opener", group: :development


group :development do
  gem 'web-console', '>= 3.3.0'
  gem 'sqlite3'
end

group :development, :test do
  # gem 'binding_of_caller'
  # gem 'better_errors'

  gem 'pry-byebug'
  gem 'pry-rails'

  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end

Try following the guide here or using this buildpack – max pleaner
They both did not work unfortunately. Do you know how i can completely delete webpack and all it dependencies from the app? – Hakeem Baba
