ruby-on-rails Heroku部署崩溃

Question

这是我从Heroku收到的消息：

应用程序错误应用程序中发生错误，无法提供您的页面。 请稍后重试。 如果您是应用程序所有者，请检查日志以获取详细信息。

这是我的Heroku日志：

有人介意解释这意味着什么吗？ 它可以在我的计算机上本地完美运行。 谢谢。

编辑： Gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.12'

gem 'devise'
gem 'simple_form'
gem 'state_machine'
gem 'draper', '~> 1.0'
gem 'js-routes'
gem 'paperclip'
gem 'will_paginate'
gem 'bootstrap-will_paginate'

group :development do
  gem 'thin'
end

group :test do
  gem 'shoulda'
  gem 'factory_girl_rails'
end

group :development, :test do
    gem 'sqlite3'
  gem 'log_buddy'
end

group :production do
    gem "pg"
end

group :assets do

问题二：薄宝石去除后。 Heroku日志：

Answer 1

当然，您的产品宝石不稀薄

从gem thin周围找到group :development 。

Heroku不需要下载成为您的Web服务器所需的gem（精简版）

编辑

对所有日志输出进行故障排除的关键是

app[web.1]: bundler: command not found: thin

这意味着捆绑程序正在尝试启动您的应用程序，但不知道所谓的thin 。 您如何“教”您的应用有关新事物的信息？ gemfile。 这就是我所经历的思考过程。

Heroku始终默认将RAILS_ENV设置为:production ，这只会安装默认或生产gemset中的gem。 这是这里的核心问题。
