Question

我创建了一个Rails 4.2.4应用程序并将其部署到Heroku而不添加任何代码。它在localhost上运行正常但在Heroku上运行不正常。这是Heroku日志：

at=info method=GET path="/" host=bagala.herokuapp.com request_id=b838aff9-e39b-4e32-8407-8d3e10da8117 fwd="178.91.253.104" dyno=web.1 connect=0ms service=3ms status=404 bytes=228

请注意，有时我会获得404状态。这很奇怪。不知道发生了什么事？

这是我的gemfile：

source 'https://rubygems.org'

ruby '2.2.0'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.4'
# Use postgresql as the database for Active Record
gem 'pg'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/rails/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder

# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use Unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'
end

group :development do
  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'

  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'
end

当然，您将收到错误404，因为这是一个全新的Rails应用程序，您没有添加任何路由。在开发环境中，Rails会显示一个欢迎页面，但在production环境中，它将是一个404页面，因为该应用程序实际上没有任何页面可以显示给用户。

在heroku上部署了Rails 4.2.4但无法运行app
