我对 Rails 应用程序比较陌生,但我有一个在本地工作的 Rails 应用程序,我正试图将其部署到 DreamHost 上的共享托管服务器。我已经关注了所有 wiki 和 stackoverflow 的问题,但我仍然没有找到答案。
我正在使用 Capistrano 进行部署,并且我已经解决了所有问题以使部署成功。但是,当我访问站点上非静态资源的任何内容时,我会收到“内部服务器错误”以及来自乘客的此错误:
Internal server error
Passenger encountered the following error:
The application spawner server exited unexpectedly: Unexpected end-of-file detected.
Exception class:
PhusionPassenger::Rack::ApplicationSpawner::Error

我可以通过 SSH 连接到服务器并手动运行“rails s”以使服务器在 3000 端口上运行,并且一切正常。
这是我的环境.rb:
# Load the rails application
require File.expand_path('../application', __FILE__)
# Initialize the rails application
LoLItemDb::Application.initialize!
# potential fix for Dreamhost shared resources
# from: http://stackoverflow.com/a/3214748/189292

大多数帖子似乎表明 gems 的路径不正确,但我已经通过搜索 Google 和 Dreamhost 的文档找到了所有配置更改。任何帮助是极大的赞赏!
