我正在尝试部署一个基本应用程序，但它无法正常工作。使用
git push heroku master
我收到了这个错误消息：

bundle exec rake -P 看起来正常工作。
我的 Gemfile 中没有什么特别的，我只是添加了 Bootstrap：
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.5.1'
# Use SCSS for stylesheets

gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views

end

gem 'spring'
end
group :production do
gem 'pg'
gem 'rails_12factor'
end
ruby "2.2.3"
好的，我不明白为什么会发生这种情况，因为我有另一个正常运行的项目。我检查了所有内容，但它仍然显示那个消息。
bundle update无效，请确保你正确使用 git：git init->git add .->git commit -m "ready for production etc.."->git push heroku master。 - RayRAILS_ENV=production bundle exec rake assets:precompile- 7urkm3n
