Database rails控制台工作，但rails服务器不工作

嗨，我遇到了一个对我来说毫无意义的问题

在我的托管服务器上，我有一个我想要运行的rails应用程序。我可以使用capistrano很好地部署应用程序。我还能够毫无问题地运行

bundle exec rails控制台产品。但是，当我尝试运行bundle exec rails服务器时，它会退出并出现以下错误

为什么我能够运行
bundle exec-rails控制台产品
，但当我尝试运行我的rails服务器时，它会抱怨适配器。它们不是都使用相同的
database.yml
文件连接到数据库吗？我的
RAILS\u ENV
是生产

谢谢
看起来您是在生产环境中显式启动控制台，在（默认）开发环境中显式启动服务器。尝试运行bundle exec rails服务器-e$rails\u ENV

。如果这不起作用，请尝试

bundle exec rails server-e production

谢谢@AmeyaSavale。顺便说一句，您可能不想在生产中使用

rails服务器。看看像和这样的应用程序服务器。我肯定会看看，但问题是我不确定我是否可以下载外部软件包。我得跟我的网络主机提供商商量一下，谢谢你提供的信息
