部署鐵軌mongo應用程序到heroku

Question

我有問題將我的Rails應用程序推向Heroku。當我嘗試在diabetes-app.herokuapp.com上登錄時，瀏覽器告訴我出現了一些問題，如果我在控制檯上做了heroku日誌，它會給我一個完整的跟蹤信息，但我不明白什麼是錯的。最後它說'Slug編譯失敗：無法編譯Ruby應用程序'。我認爲它應該與Rails資產管道有關，因爲如果我做git push heroku master一切都很順利，直到它開始爲Rails資產管道準備應用程序。從遠程的線上觀察：----->爲Rails資產管道準備應用程序我知道，僅僅通過這些信息解決問題並不容易，但有點暗示問題的根源在哪裏會很大。

這是做混帳推Heroku的主

的痕跡，我覺得這是顯示的第一個錯誤，當我做的Heroku記錄

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

這充分的最後一條消息跟蹤

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

編輯

這是我的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 

這是我的配置/環境/ 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 

這是我的Gemfile

source 'https://rubygems.org' 

gem 'rails', '4.1.7' 
gem 'gon' 
gem 'sass-rails', '~> 4.0.3' 
gem 'uglifier', '>= 1.3.0' 
gem 'jquery-rails' 
gem "d3-rails" 
gem 'turbolinks' 
gem 'jbuilder', '~> 2.0' 
gem "mongoid", '~> 4.0.0' 
gem 'devise' 

group :development, :test do 
    gem 'rspec-rails', '~> 3.0' 
    gem 'cucumber-rails', :require => false 
    gem 'factory_girl_rails' 
    gem 'database_cleaner' 
    gem 'pry' 
    gem 'validates_timeliness', '~> 3.0' 
    gem 'timecop', '0.7.1' 
    gem 'awesome_print' 
    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+
