ruby-on-rails - 为什么我在运行 rails 控制台时会收到此错误？

问题描述

运行 rails 控制台时出现错误，其他一切似乎都运行良好。我可以在没有任何错误日志的情况下启动服务器。

Running via Spring preloader in process 13744

我已经安装了irb

$ whereis irb                                                                                                                    1 ↵
irb: /home/archie/.rbenv/shims/irb /home/archie/.gem/ruby/2.6.0/bin/irb

并将其添加到路径中。
