我的应用程序在本地运行良好，当我输入 git push heroku master 时我没有看到任何错误。但是，当我输入 heroku open 并访问我看到的网址时：

应用程序错误

应用程序发生错误，无法提供您的页面。请稍后重试。如果您是应用程序所有者，请查看您的日志以获取详细信息。

在heroku日志中，我得到以下信息：

有一个加载错误和一些我没有设法修复的弃用警告。我刚刚更新到 rails 3.2.11 不确定它是否相关。

宝石文件：

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

这是我第一次在这台（新）计算机上推送 heroku，不确定这是否会导致问题。

输入 git push heroku 时，我也收到此错误：

   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?

现在调查：https ://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar

看起来您正在使用默认的 WEBrick 服务器。Heroku 建议使用“瘦”服务器。尝试在 Gemfile 中添加类似的内容：

gem 'thin', :group => :production

然后运行 ​​bundle install，使用 Git 提交文件并再次推送到您的 heroku 应用程序。如果您还没有这样做，则需要通过在命令行中尝试以下命令来预编译资产：

RAILS_ENV=production bundle exec rake assets:precompile

然后，不要忘记运行你的 git 命令：

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