ruby - Heroku:未找到且进程已退出

Question

我不知道如何调试这个。在本地运行这个 ruby​​/sinatra/thin 应用程序我没有任何问题。然而，在 Heroku 上，该应用程序似乎无法加载，显示“未找到”。我不知道如何理解日志:

有什么想法吗？

我的 gem 文件

source "http://rubygems.org"

# Sinatra
gem "rake"
gem "thin"
gem "sinatra", "~> 1.3.4"
gem "sinatra-contrib", "~> 1.3.1"
gem 'sinatra-assetpack', :require => 'sinatra/assetpack'

# Sass

# Mailing related

# Google Analytics: UNCOMMENT IF DESIRED, THEN ADD YOUR OWN ACCOUNT INFO TO config.ru
#gem 'rack-google-analytics', "~> 0.9.2"

我的config.ru

require 'rubygems'
require 'bundler'

Bundler.require

require './app.rb'
run Sinatra::Application

Answer 1

我克隆了该存储库，但无法通过 rackup 使其工作，而这是 Heroku 运行应用程序所依赖的。当直接通过 Ruby 运行 Sinatra 应用程序时，它确实有效。以下是我所做的更改，使其能够与 rackup 一起使用:

config.ru

require 'rubygems'
require 'bundler'

Bundler.require

require File.expand_path 'app.rb', File.dirname(__FILE__)
run App

If you've subclassed, run the subclass, otherwise use Sinatra::Application

我还删除了我发现的所有$:.unshifts，因为它们是邪恶的。
