Ruby on Rails 应用程序无法启动答案

【问题标题】：Ruby on Rails application could not be startedRuby on Rails 应用程序无法启动
【发布时间】：2010-09-27 16:18:44
【问题描述】：

我正在尝试部署一些更改，但我无法看到它们，因为我收到的 URL 在 Phusion 错误页面“无法启动 Ruby on Rails 应用程序”上发送给我。

当我检查日志时，我得到如下信息：

Exception ArgumentError in PhusionPassenger::Railz::ApplicationSpawner (syntax error on line 36, col 1: ` sdc_id: dcsvdln1l00000kv1qsmc4oob_1p3v')

我完全不知道发生了什么，任何帮助将不胜感激。

提前致谢，

罗尔夫

【解决方案1】：

如果没有更多信息，您似乎在某处的 yaml 文件中有错误。也许有没有得到解决的冲突？对 sdc_id 执行 grep 并查看您看到的内容。

是的，你可以看到你的 environment.rb 正在加载一个 yaml 文件。看看你的配置文件夹，我敢打赌那里有一些古怪的东西。
raw_config = File.read(RAILS_ROOT + "/config/config.yml") APP_CONFIG = YAML.load(raw_config)[RAILS_ENV] APP_CONFIG 的最后一行似乎是原因，尽管它有效与具有完全相同文件的其他项目很好......我真的很无能为力:(
config.yml 中确实有一个额外的行：'(
