检查过 StackOverflow 中建议添加库的类似问题：

'解决替换' 和更改文件： /etc/hosts

/etc/resolv.conf

但没有解决方案。我开始了，所以我对应该看的地方没有足够的知识。感谢您的指导。

解决了这个问题： > rails server -p 3000 -b 127.0.0.1 但是奇迹或魔法并不是一个很好的解释。有什么我失败的想法吗？

标签： ruby-on-rails ruby ruby-on-rails-5

【解决方案1】：

谢谢，'> rails server -p 3000 -b 127.0.0.1' 也适用于我！更新到 git 后我遇到了这个问题。重新启动终端和计算机没有工作。奇怪，不知道是不是DNS问题。

是的，我试过了，但我的声望不够 50，无法发表评论。我只是想支持答案，因为这是一个棘手的问题。
