無法將我的rails應用程序推送到heroku，說有一個gemfile錯誤

Question

我是一個新手，試圖將我的rails應用程序推送到heroku但是它說推送拒絕了。

我在stackoverflow上看了一些類似的問題，但沒有一個解決方案似乎能解決它。

這是終端的代碼

這是我的Gemfile

source 'https://rubygems.org'
ruby '2.4.4'

gem 'bootsnap', require: false
gem 'devise'
gem 'jbuilder', '~> 2.0'
gem 'pg', '~> 0.21'
gem 'puma'
gem 'rails', '5.2.1'
gem 'redis'

gem 'autoprefixer-rails'
gem 'font-awesome-sass', '~> 5.6.1'
gem 'sassc-rails'
gem 'simple_form'
gem 'uglifier'
gem 'webpacker'

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

group :development, :test do
  gem 'pry-byebug'
  gem 'pry-rails'
  gem 'listen', '~> 3.0.5'
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
  gem 'dotenv-rails'
end

任何幫助都將非常感激。 謝謝！

嘗試手動安裝bundler

gem install bundler -v 1.17.3
bundle _1.17.3_ install
git commit -am "Bundler 1.17.3 was installed"
git push heroku master
