我整天都在用头撞墙。由于某种原因，我向 Rails 4 的过渡并不顺利。

在本地一切正常。我在这里遵循了 Railscast 示例http://railscasts.com/episodes/415-upgrading-to-rails-4

但是，我不断收到“应用程序错误”消息。

我已经转换为强参数，删除了最初的 gem 以帮助过渡，但似乎无法弄清楚我做错了什么。

这是我的 Gemfile：

source 'https://rubygems.org'

gem 'rails', '4.0.0'
ruby '2.0.0'
gem 'taps'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :production do
  gem 'pg'
  gem 'unicorn'
  gem 'newrelic_rpm'
end
group :development, :test do
  gem 'sqlite3'
  gem 'meta_request', '~> 0.2.8'
end

gem "rmagick", '2.13.2'
gem "carrierwave"
gem 'aws-sdk'
gem 'fog'
gem 'carrierwave_direct'
gem 'sidekiq'


# Gems used only for assets and not required
# in production environments by default.

  gem 'sass-rails',   '~> 4.0.0'
  gem 'coffee-rails', '~> 4.0.0'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 2.2.1'
  gem "therubyracer"
  gem "less-rails"
  gem 'twitter-bootstrap-rails', '~> 2.2.8'


gem 'rake', '~> 10.1.0'
gem 'jquery-rails'
gem 'cancan'

#to have some backward compatability with Rails 3
# gem 'protected_attributes'
gem 'rails-observers'
gem 'actionpack-page_caching'
gem 'actionpack-action_caching'
# end of backward compatibility section

# To use ActiveModel has_secure_password
 gem 'bcrypt-ruby', '~> 3.0.0'

这是我的 Heroku 日志：

今天早上一切正常。我已经仔细检查了 DNS，那里的一切似乎都设置得很好。

我已经尝试迁移数据库并重新启动应用程序。到目前为止没有运气。

非常感谢任何帮助。我知道我一定忽略了一些东西。

来自https://devcenter.heroku.com/articles/ruby-versions：

$ rake rails:update:bin

这将在应用程序的根目录中生成一个 bin 目录。确保它不在您的 .gitignore 文件中，并将该目录及其内容检查到 git 中。

你检查过你的.gitignore文件吗？
