【中文标题】将带有 Sinatra 2.0.0beta2 的 Rails 5 应用程序部署到 Amazon Linux AMI 时出错

【英文标题】：Error deploying Rails 5 app with Sinatra 2.0.0beta2 to Amazon Linux AMI

【问题描述】：

我遇到了 Sinatra 2.0.0 beta 2 和 Rails 5 部署到 Amazon Linux AMI v 2.1.6 的异常。我已经在 Sinatra Github repro 中发布了the issue，但有人建议我在这里发布。

编辑：我在使用 Elastic Beanstalk 时遇到了这个问题，但正如 @neal 报告的那样，Capistrano 部署到 EC2 时也会发生这种情况。

重现问题的步骤如下：

在干净的目录中创建一个新的 Rails 5 应用程序

$ gem install rails
$ rails --version
(confirm Rails 5.0.0.1)
$ rails new test-app

将此行添加到 gemfile：

gem 'sinatra', '2.0.0.beta2'

创建一个类型为“64bit Amazon Linux 2016.03 v2.1.6 running Ruby 2.3 (Puma)”的新 Elastic Beanstalk Web 环境，Web 服务器。使用所有默认值，除了将实例大小更改为 t2.small（任何更小的都没有足够的内存来部署）

使用 Web 控制台将两个新环境变量添加到 Elastic Beanstalk 环境 SECRET_KEY_BASE =（为此设置一个值） RAILS_ENV = 生产

将应用程序部署到这个新环境，例如使用 eb 命令行工具。

再次部署 通过 Elastic Beanstalk 控制台跟踪日志

结果：

【问题讨论】：

仍然存在于最新的 Amazon Linux AMI 2016.09 v2.2.0

【参考方案1】：

这不仅仅是弹性 bean stalk 问题，我可以确认在使用 capistrano / EC2 Ubuntu / nginx 部署 rails 5 应用程序时也会发生这种情况

【讨论】：

感谢@neal，我编辑了帖子以反映这不是 Elastic Beanstalk 特有的。你介意提出这个问题吗？
