heroku应用程序崩溃，但本地伟大工程

Question

我的应用程序在本地完美地工作，我看到没有错误，当我输入git push heroku master。然而，当我键入Heroku的开放和访问URL我看到：

应用程序错误

在应用程序中出现错误，你的页面无法送达。请稍后重试。 如果您是应用程序所有者，请查看日志以获取详细信息。

在Heroku的日志中我得到以下几点：

有一个负载错误，我没有带管理一些自嘲的警告来修复。我只是更新到轨3.2.11不知道它是否相关。

的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.11' 
gem 'bootstrap-sass', '2.0.4' 
gem 'bcrypt-ruby', '3.0.1' 
gem 'faker', '1.0.1' 
gem 'will_paginate', '3.0.3' 
gem 'bootstrap-will_paginate', '0.0.6' 
gem 'jquery-rails', '2.0.2' 
gem 'pg', '0.12.2' 
gem 'rails_autolink', '~> 1.0.9' 
gem 'rinku', '~> 1.5.0', :require => 'rails_rinku' 
gem 'auto_html', '1.6.0' 
gem 'acts_as_votable', '~> 0.4.0' 
gem 'thumbs_up', '~> 0.6.2' 


group :development, :test do 
    gem 'rspec-rails', '2.11.0' 
end 

group :development do 
    gem 'annotate', '2.5.0' 
end 

group :assets do 
    gem 'sass-rails', '3.2.5' 
    gem 'coffee-rails', '3.2.2' 
    gem 'uglifier', '1.2.3' 
end 

group :test do 
    gem 'factory_girl_rails', '4.1.0' 
    gem 'capybara', '1.1.2' 
    gem 'cucumber-rails', '1.2.1', :require => false 
    gem 'database_cleaner', '0.7.0' 
end 

这是第一次即时推送到Heroku的这个（新）电脑不知道这是否有助于问题上。

我打字混帐推Heroku的时候也出现此错误：

Running: rake assets:precompile 
    rake aborted! 
    could not connect to server: Connection refused 
    Is the server running on host "127.0.0.1" and accepting 
    TCP/IP connections on port 5432?

看起来你使用的是默认的WEBrick服务器。 Heroku建议使用“瘦”服务器。尝试在你的Gemfile添加这样的事情：

gem 'thin', :group => :production 

然后运行捆绑安装，使用Git提交的文件，并再次推到你的Heroku应用。 如果您还没有这样做，你需要在你的命令行tryping以下预编译的资产：

RAILS_ENV=production bundle exec rake assets:precompile 

然后，不要忘了运行git的命令：

git add . 
git commit -m "added precompiled assets" 
git push heroku master
