我遇到了一些麻烦（第二天我正在尝试），只需将rails的基本应用程序结构部署到heroku。基于这个基本结构，我后来想要做一些改变和改进工作，但对于初学者我只想验证它是否正常工作。
我的步骤： 1.我之前安装了一些ruby和rails，但是我按照本指南安装了最新的稳定红宝石和导轨：http://railsapps.github.io/installing-rails.html 2.我有一个〜/ ruby / myapp文件夹，其中我有以下版本：
ruby 2.1.2p95 (2014-05-08 revision 45877) [i686-linux]
Rails 4.1.1
rails new。
ruby 2.1.2
到Gemfile - 再次提交 Heroku再次运行bundle install
您要查找的页面不存在。
您可能输错了地址或页面可能已移动。
如果您是应用程序所有者，请检查日志以获取更多信息。
查看heroku日志时，请输入以下消息：

我非常感谢你的帮助，因为这是我第二天尝试通过查看论坛（SE）来完成一项简单的任务，而不是。并没有效果。虽然我在更新到ruby 2.1.2和rails 4.1.1之前尝试过至少4-5次。之后几次。
我对这个配置奥德赛变得非常非常沮丧。

您收到的错误消息是来自rails的404错误，在生产中您没有看到rails欢迎页面。
如果您创建一个简单的HomeController并渲染Hi或者其他内容，并将其设置为您的根URL，它可能会有效！
应用/控制器/ home_controller.rb
class HomeController < ApplicationController
def index
end
end
应用/视图/家/ index.html.erb
<p>Hi</p>`
<强>配置/ routes.rb中
root to: 'home#index'`

您是否可以修改production.rb以确保提供静态资产：
config.serve_static_assets = true
尝试将以下内容添加到Gemfile中：
gem 'rails_log_stdout', github: 'heroku/rails_log_stdout'
gem 'rails3_serve_static_assets', github: 'heroku/rails3_serve_static_assets'
您正在使用Webrick服务器，尝试使用独角兽，使Gemfile制作组如下：
group :production do
gem 'pg'
gem 'unicorn'
gem 'rails_log_stdout', github: 'heroku/rails_log_stdout'
gem 'rails3_serve_static_assets', github: 'heroku/rails3_serve_static_assets'
end
