Ruby Rails的错误 [英] Ruby rails s error

问题描述

当我尝试运行 rails s 时，我遇到了一个大错误，我刚刚重新安装了ruby和PostgreSQL。感谢帮助。这也是在我运行 rails s 之后，如果有任何可能的方式对我有帮助，我也发表了另一篇有关类似问题的文章Rails Forem安装帮助我仍然对Ruby真的很陌生，只是为了牢记这一点。再次感谢。

I'm getting this massive error when I try to run rails s, I've just re installed ruby as well as PostgreSQL. Thanks for help. This was right after I ran rails s also, i've made a other post on similar issues if that helpes at all in any way possible Rails Forem installation assistance i'm still really new with Ruby just to keep that in mind. thanks again.
