上限生产部署失败，并出现ActiveRecord :: NoDatabaseError：致命：数据库“ rails / rbwapp”不存在

问题描述

我的开发机器上有一个空的Rails应用程序。 我一直在遵循https://gorails.com/deploy/ubuntu/20.04上的教程，以便将其部署到新的DigitalOcean ubuntu 20.04 Droplet。

我会逐步完成整个教程，并进入运行部署的步骤：

从数据库“ rails / rbwapp”不存在的意义上说，该错误是正确的，但是也不应该这样。它应该寻找“ rbwapp_production”（确实存在）

我被困住了。任何建议，不胜感激...
