第一次来电，长时间听众。我在AWS Elastic Beanstalk Web服务器环境中运行了一个没有问题的rails应用程序，现在我想将类似的应用程序部署到工作线程环境，以对上传文件进行异步处理。就目前而言，为了实现这一目标，我正在将相同版本的应用程序（换句话说，在多个Web服务器环境中运行良好的版本）部署到工作环境（使用与Web服务器环境相同的平台） ，但是当它尝试执行初始rake assets:precompile时，我得到一个RubyVersionMismatch：

我的Gemfile确实调用了v2.2.2，但是如果你注意到，堆栈跟踪的底部两行显示正在调用的ruby存在于/ opt / elasticbeanstalk中，尽管chruby正确地找到了并从/ opt / rubies / ruby-current中选择版本2.2.2。任何想法为什么会这样？如果EB将随机回归到自己的本地版本，那么基于containerconfig动态选择ruby版本有什么意义呢？
