使用乘客部署Ruby on Rails应用程序时出错

Question

部署Rails应用程序时收到以下错误。 这是什么意思，我该如何解决？ 该应用程序在我的本地计算机上运行。 唯一的区别是我的本地机器上没有乘客。

Ruby（机架）应用程序无法启动。

应用程序所需的源文件丢失。

您可能没有正确上传应用程序文件。 请检查您的所有应用程序文件是否都已上传。

可能未安装必需的库。 请安装此应用程序所需的所有库。

有关错误的更多信息可能已写入应用程序的日志文件。 请检查它以分析问题。

错误消息：无法加载此类文件-URI

异常类：LoadError

应用程序根目录：/ home / autobrain / Autobrain

Answer 1

在Apache上，尝试通过在.conf文件中添加该passenger指令来设置环境，如下所示：

RailsEnv development

然后重新启动apache！
