Question

我的所有文件都可以在GitHub上找到：https://github.com/Integralist/Passage（以防您需要查看我正在使用的内容）。

我是Heroku的新用户，我尝试按照上传Sinatra应用程序的说明进行操作，但它没有运行，当我访问应用程序URL时，我收到一条通用的“应用程序错误”消息。

我的设置过程如下：

heroku login
heroku create --stack cedar

创建config.ru文件并添加内容...

require 'app'
run Sinatra::Application

创建Gemfile文件（无文件扩展名）并添加内容...

source 'http://rubygems.org'
gem 'sinatra', '1.3.2'
gem 'thin', '1.3.1'

打开终端（我正在运行Mac OS X）并执行：bundle install这似乎生成了一个重复的Gemfile但这次使用.lock文件扩展名？这个其他Gemfile现在有以下内容......

GEM
  remote: http://rubygems.org/
  specs:
    daemons (1.1.8)
    eventmachine (0.12.10)
    rack (1.4.1)
    rack-protection (1.2.0)
      rack
    sinatra (1.3.2)
      rack (~> 1.3, >= 1.3.6)
      rack-protection (~> 1.2)
      tilt (~> 1.3, >= 1.3.3)
    thin (1.3.1)
      daemons (>= 1.0.9)
      eventmachine (>= 0.12.6)
      rack (>= 1.0.0)
    tilt (1.3.3)

PLATFORMS
  ruby

DEPENDENCIES
  sinatra (= 1.3.2)
  thin (= 1.3.1)

然后我创建一个Procfile（没有文件扩展名）并添加内容：web: bundle exec ruby app.rb -p $PORT（app.rb显然是我的主应用程序文件的名称）。

然后我使用Git将我的文件暂存/提交/推送到相关的Heroku repo。

但如果我跑heroku ps我就会......

=== web: `bundle exec ruby app.rb -p`
web.1: crashed for 1m

然后如果我跑heroku logs我就会......

有人可以解释问题是什么以及如何解决它。

感谢。

/app/vendor/bundle/ruby/1.9.1/gems/sinatra-1.3.2/lib/sinatra/main.rb:15:in `<class:Application>': missing argument: -p (OptionParser::MissingArgument)

这是它在堆栈跟踪中给出的错误。当它运行bundle exec ruby app.rb -p时，没有给出-p的参数。您需要bundle exec ruby app.rb -p 3000之类的东西（在端口3000上运行）。也许全局变量$ PORT没有被定义？

修改

虽然形成heroku's docs on the Procfile：

You can reference other environment variables populated by Heroku, most usefully the $PORT variable, in the command.

尝试执行raise $PORT.inspect，然后推送到heroku。它会崩溃，但希望更好地了解它正在尝试做什么。

无法获得与Heroku一起使用的基本Ruby / Sinatra应用程序？
