Ruby Passenger + Nginx - 错误代码解释：HTTPStatus.NOT_FOUND - 没有任何内容与给定的 URI 匹配

Question

我在尝试使用 capistrano/nginx 和乘客部署我的 Rails 应用程序时遇到错误，capistrano 工作正常，我可以很好地运行我的部署命令，但是由于来自乘客 gem 的错误，我无法访问我的端点。

这是在乘客尝试访问我的域时创建的临时 html 文件中记录的错误。

`错误响应 错误代码：404

消息：找不到文件。

错误代码解释：HTTPStatus.NOT_FOUND - 没有任何内容与给定的 URI 匹配。`

这就是您查看页面时显示的内容。

We're sorry, but something went wrong. The issue has been logged for investigation. Please try again later.

这是 nginx 错误日志显示的内容

这就是我的 gemfile 的样子（这是一个旧的 ruby 应用程序，我计划在部署设置后升级）

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

我正在按照本教程进行操作，其他项目也遵循该教程，在同一托管 DigitalOcean VPS ubuntu 22.04 LTS 上运行时没有出现这些问题

本来打算向乘客开一张问题票，但上面说要先尝试 stackoverflow。

Answer 1

如果您遇到此问题，似乎无法找到该乘客具体抱怨的文件。最终对我有用的是将 ruby 版本从 2.6.1 升级到 2.7.1 ，重新安装捆绑器以及所有 gem。然后使用

重新部署应用程序

cap production deploy

我希望有一个更好的解决方案，但 2.6.1 已经相当过时了，无论如何我都计划升级，跳到 2.7.1 为我解决了这个问题，没有任何其他更改。
