部署铁轨mongo应用程序到heroku

Question

我有问题将我的Rails应用程序推向Heroku。当我尝试在diabetes-app.herokuapp.com上登录时，浏览器告诉我出现了一些问题，如果我在控制台上做了heroku日志，它会给我一个完整的跟踪信息，但我不明白什么是错的。最后它说'Slug编译失败：无法编译Ruby应用程序'。我认为它应该与Rails资产管道有关，因为如果我做git push heroku master一切都很顺利，直到它开始为Rails资产管道准备应用程序。从远程的线上观察：----->为Rails资产管道准备应用程序我知道，仅仅通过这些信息解决问题并不容易，但有点暗示问题的根源在哪里会很大。

这是做混帐推Heroku的主

的痕迹，我觉得这是显示的第一个错误，当我做的Heroku记录

ActionController::RoutingError (No route matches [GET] "/javascripts/devise/sessions.js"): 

这充分的最后一条消息跟踪

2015-06-15T13:46:53.863680+00:00 heroku[slug-compiler]: Slug compilation failed: failed to compile Ruby app 

编辑

这是我的application.rb中

require File.expand_path('../boot', __FILE__) 
require "action_controller/railtie" 
require "action_mailer/railtie" 
require "rails/test_unit/railtie" 
require "sprockets/railtie" 


Bundler.require(*Rails.groups) 

module DiabetesApp 
    class Application < Rails::Application 

    config.assets.initialize_on_precompile=false 

    rake assets:precompile 
    end 
end 

这是我的配置/环境/ production.rb

Rails.application.configure do 
    config.cache_classes = true 
    config.eager_load = true 
    config.consider_all_requests_local  = false 
    config.action_controller.perform_caching = true 
    config.serve_static_assets = false 
    config.assets.js_compressor = :uglifier 
    config.assets.compile = false 
    config.log_level = :info 
    config.i18n.fallbacks = true 
    config.active_support.deprecation = :notify 
    config.log_formatter = ::Logger::Formatter.new 

end 

这是我的Gemfile

source 'https://rubygems.org' 

gem 'rails', '4.1.7' 
gem 'gon' 
gem 'sass-rails', '~> 4.0.3' 
gem 'uglifier', '>= 1.3.0'

gem 'turbolinks'

group :development, :test do 
    gem 'rspec-rails', '~> 3.0'

    gem 'pry' 
    gem 'validates_timeliness', '~> 3.0' 
    gem 'timecop', '0.7.1'

    gem 'guard-rails' 
end 

group :test do 
    gem 'shoulda-matchers', require: false 
    gem "capybara-webkit" 
end 

group :production do 
    gem 'rails_12factor' 
    gem 'thin' 
end 

Answer 1

正如documentation in the configuration part提到

Open myapp/config/application.rb and near the top

remove the line require "rails/all" and add the following lines so you end up with this

require "action_controller/railtie" 
require "action_mailer/railtie" 
require "active_resource/railtie" # Comment this line for Rails 4.0+ 
require "rails/test_unit/railtie" 
# require "sprockets/railtie" # Uncomment this line for Rails 3.1+
