我想将我的 Rails 应用程序部署到 Heroku。当然，我还包括一些额外的 gem，例如“devise”或“rails_admin”。我严格遵循 Rails Girls 的教程 (http://guides.railsgirls.com/heroku/)。我在运行 git push heroku master 时遇到了一些非常烦人的问题。

这是我的 Gemfile:
source 'https://rubygems.org'
gem 'rails', '4.2.0.rc3'
group :development do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'rails_12factor'
end
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :production, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring'
gem 'bootstrap-generators', '~> 3.3.1'
gem 'simple_form', :git => 'git://github.com/plataformatec/simple_form.git'
gem 'rails_admin'
gem 'mocha'
gem 'nifty-generators'
gem 'jquery-turbolinks'
gem 'devise'
end
问题一定出在 rake assets:precompile 上。
谁能帮帮我？这个问题确实拖慢了我的 Rails Adventure。
最佳答案
你的 gem 都没有
group :development, :production, :test do
是根据 Heroku 日志安装的。尝试将它们放在组之外。
