在 Heroku 上部署简单的机架应用程序时出现应用程序错误答案

【问题标题】：Application Error when deploying a simple rack application on heroku在 Heroku 上部署简单的机架应用程序时出现应用程序错误
【发布时间】：2013-01-18 19:33:15
【问题描述】：

我正在尝试在 heroku 上部署我的应用程序它包含5个文件 1.config.ru 带代码

require 'rack'
require './myapp'

run MyApp.new

2.Gemfile 带代码

source "http://rubygems.org"
gem 'grape'
gem 'sequel'
gem 'heroku'
gem 'rake'
gem 'pg'
gem 'rack'
group :test do
  gem "rspec", "~> 2.12.0"
  gem "rack-test", "~> 0.6.2"
  gem "rspec-core", "~> 2.12.2"
  gem "rspec-expectations", "~> 2.12.1"
  gem "rspec-mocks", "~> 2.12.1"
  gem "capybara", "~> 2.0.2"
  gem "nokogiri", "~> 1.5.6"
end

3.自动创建的Gemfile.lock 4.myapp.rb 带代码

# my_app.rb
class MyApp
  def call env
    [200, {"Content-Type" => "text/html"}, ["Hello Rack Participants"]] 
  end
end

5.Procfile 和代码

web: bundle exec rackup config.ru

然后我调用捆绑安装

在那之后 config.ru 它按预期工作得很好但之后我尝试在heroku上部署它并得到应用程序错误我为此执行了以下命令

git init
git add .
git commit -m "initial commit"
heroku create
git push heroku master
heroku open

Web 浏览器打开时出现应用程序错误当我运行命令 heroku logs 然后它给我日志

2013-02-04T05:34:17+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=quiet-caverns-8170.herokuapp.com fwd=121.245.34.235 dyno= queue= wait= connect= service= status=503 bytes=

谁能帮助我为什么在heroku上遇到这个错误并希望纠正它？？

【问题讨论】：

我会查看您发布的行之前和之后的行，有时会有更多信息。当我不得不执行 db:migrate but for to 时，我遇到了类似的问题。
不，您可以看到没有数据库迁移，它是一个简单的 rake 应用程序等待发布完整日志
现在请帮助我为什么会收到此错误
它说“bundle: command not found”，如果它是一个 rails 应用程序 heroku 知道并在运行 bundle install 和启动 rails 之前安装 bundler；你试过没有procfile吗？

标签： ruby-on-rails heroku rack heroku-toolbelt heroku-san

【解决方案1】：

您似乎没有为应用程序指定正确的运行端口。尝试将您的 Procfile 切换到以下内容

web: bundle exec rackup config.ru -p $PORT -E $RACK_ENV

有关类似问题，请参阅 Deploy Sinatra app on Heroku 和 Deploying sinatra app (with config.ru) on heroku cedar stack。

【讨论】：

【解决方案2】：

您没有绑定到$PORT 中的端口，因此我们终止了您的进程。您必须更改您的 Procfile 以包含 -p $PORT。
