我正在尝试在 heroku 上部署一个示例 rails 应用程序。在创建一个非常基本的应用程序、添加一个 git 存储库、提交所有内容和“heroku create”之后，我将它推送到 heroku。终端中完全没有错误，但是当我使用正确的地址打开浏览器时，我得到以下信息：

The page you were looking for doesn't exist.

You may have mistyped the address or the page may have moved.

我已经搜索了三个小时并使用了关于如何部署应用程序的 heroku 教程，但我就是不知道我做错了什么。这是我的 Gemfile：

source 'https://rubygems.org'

ruby '2.0.0'

gem 'rails', '4.0.0.beta1'

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

gem 'json'

group :production do
  gem 'pg'
  gem 'rails', '4.0.0.beta1'
  gem 'railties', '4.0.0.beta1'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  #gem 'sass-rails',   '~> 3.2.3'
  gem 'sass-rails',   '~> 4.0.0.beta1'
  #gem 'coffee-rails', '~> 3.2.1'
  gem 'coffee-rails', '~> 4.0.0.beta1'

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

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

上面的步骤我重复了几次，还是不行。谢谢！

编辑：添加了heroku控制台日志：

首先，这里有一个很好的 Rails 路由指南。

假设您的应用程序中有一个Article模型和一个文章控制器，您必须在 config/routes.rb 下定义此资源的路由。Rails 允许您在一行中添加index, show new, create, edit, update路线destroy：

resources :articles

这将映射到以下内容：

GET     /articles           index   display a list of all articles
GET     /articles/new       new     return an HTML form for creating a new article
POST    /articles           create  create a new article
GET     /articles/:id       show    display a specific article
GET     /articles/:id/edit  edit    return an HTML form for editing a article
PUT     /articles/:id       update  update a specific article
DELETE  /articles/:id       destroy delete a specific article

但是，要确保主页路由到您需要root在 config/routes.rb 下定义的这些操作之一

root to: "articles#index"

然后再次提交并推送到heroku。

我注意到您正在尝试（可能是无意的）使用导轨的“边缘”版本（4+）。

我现在会坚持使用 3.x 版本，这就是本教程可能假设的内容。

您可以使用它来创建具有特定版本的应用程序（在这种情况下为 3.2）

rails _3.2_ new myapp

如果您的系统上没有该版本的 rails，您可能需要安装它，例如

gem install -v=3.2 rails

或者，如果失败了，

sudo gem install rails -v3.2

以上就是为什么，当您按照当前的 Heroku 说明进行操作时，它假定 rails 3 并且该版本确实执行该默认根路径和 public/index.html 文件
