在 Elastic Beanstalk 上部署时出错 - Rails

Posted 2023-03-04

【中文标题】在 Elastic Beanstalk 上部署时出错 - Rails

【英文标题】：Error Deploying on Elastic Beanstalk - Rails

【发布时间】：2019-05-25 01:21:15

【问题描述】：

我正在尝试在 Elastic Beanstalk 上部署自定义项目，但是当 puma 启动时，我的 puma.log 文件中出现以下错误。我不知道如何解决这个问题。我认为它可能与我的 yaml 解析器有关，但我不完全确定如何使用 EB 更新它。任何帮助将不胜感激。

我今天再次查看了日志以确保我没有遗漏任何内容，并且我确实在不同的日志文件中看到了对相同错误的另一个引用，但它仍然告诉我很少。

【问题讨论】：

您在部署过程中得到的究竟是什么日志？另外，你可以去 eb 仪表板和日志获取最后 100 行日志吗？

@7urkm3n 这就是 puma.log 文件中的确切错误。仪表板仅显示我的整体实例运行状况的状态为 Warning，而我的单实例状态的状态为 Degraded。尝试从浏览器访问站点时出现 504 Gateway Timeout 错误。

不，您必须转到 EB 仪表板/日志并获取最后一个日志。它应该与我记得的不同。我不知道psych.rb 行line 83 是什么。确保在 localhost 1st 中运行生产应用程序。

是的，这就是这个错误来自“EB 仪表板/日志并获取最后一个日志”的地方。顺便说一句，我在 Heroku 服务器上运行了这个应用程序，但出于定价目的，我正在迁移到 AWS。 @7urkm3n

请使用code block 而不是内联代码正确格式化您的堆栈跟踪。

【参考方案1】：

如果app/shared/assets 下有任何 .json 清单文件，请尝试删除它们。

此错误也可能由于 YAML 文件错误而产生。您可以通过运行这个小脚本（在 Rails 根目录中）来检查这一点，该脚本在所有子目录中递归查找所有 *.yml 文件并测试该文件。

require 'yaml'

d = Dir["./**/*.yml"]
d.each do |file|
  begin
    puts "checking : #file"
    f =  YAML.load_file(file)
  rescue StandardError
    puts "failed to read #file: #$!"
  end
end
