ruby-on-rails - Heroku Rails 应用程序在 HTTP 请求时立即崩溃

Question

我的 Rails 应用程序在本地运行良好，但在 Heroku 上运行不正常。我可以毫无意外地调用 heroku run rake db:migrate 和 heroku run rake db:reset，但是一旦我向应用程序发出 HTTP 请求，它就会立即崩溃。这是 heroku info 的输出:

Addons:        Basic Logging, Basic Release Management, Shared Database 5MB
Database Size: 1M
Git URL:       git@heroku.com:blazing-dawn-5661.git
Repo Size:     52M
Slug Size:     53M
Stack:         cedar
Web URL:       http://blazing-dawn-5661.herokuapp.com/

这是向应用程序发出 HTTP 请求后 heroku logs 的输出(这里似乎没有什么特别有用的):

看看这个:

Heroku 上的 Ruby 1.9.3 和 Rails 3.2

Heroku 的最新堆栈“Celadon Cedar”支持 Rails 3.2，但默认安装 Ruby 1.9.2。 Rails 3.2 推荐使用 Ruby 1.9.3。

您可以配置 Heroku 环境以使用 Ruby 1.9.3。

注意:Heroku 明确表示 Heroku 上的 Ruby 1.9.3 是实验性的，这意味着“不支持，ruby_version 将来会更改，并且此功能可能会在没有警告的情况下更改或删除”在回应 2012 年 1 月 31 日的询问时，Heroku 表示，“还没有时间表”来全面支持 Ruby 1.9.3。

注意:之前(2012 年 3 月 19 日之前)在 Heroku 上安装 Ruby 1.9.3 需要安装 heroku-labs 插件。 heroku-labs 插件已弃用，其功能现已合并到 heroku 客户端 gem 中。
