如何使用 rails 控制台命令更正错误? [英] How Do I Correct An Error with rails console command?

问题描述

当我在 Rails 应用程序的根目录中时，我可以成功执行 rails server.但是，当我尝试执行 rails console 或 rails c 时，出现以下错误.

When I'm in the root directory of my Rails app I can successfully execute rails server. However when I try to do rails console or rails c I get the following error.
