Rails路由在部署中中断

Question

经过多年的开发，包括在Heroku上部署，我正在跟随Ryan Bates的Railscast部署到VPS（Linode）进行升级。一切顺利部署，独角兽启动，然后在我请求的任何路线上抛出错误，即（这是一个简单的页面#welcome请求）：

Started GET "/welcome" for 108.74.161.183 at 2014-09-15 22:02:43 +0000

ActionController::RoutingError (No route matches [GET] "/welcome"):

无论我是启动unicorn还是unicorn_rails，性能都是相同的。当我在服务器上运行“rake routes”时，它会尽职地列出它应该的所有路由。除了路由失败之外，我不明白的一件事是有关调试器请求的内容。我的代码中没有调试器调用，在/ app或/ lib中。但我没有看到调试器警告（之前从未出现问题）和路由故障之间存在任何关联。

我坐在这里撕扯我的头发，因为我无法想象这可能是什么问题的根源。非常感谢任何富有成效的建议。

Answer 1

答案：似乎很久以前我试图通过使用一个标志来记住路由的加载，以防止在routes.rb中多次执行加载代码。出于某种原因，Rails决定在该标志的生命周期中重新加载它们两次，结果是第二次加载被阻止，导致......没有路由！这不是平台问题，而是环境问题，分期是唯一的受害环境。我不知道为什么路由会在分段中重新加载而不是在开发或生产中，但这是问题的根源。
