问题描述
我还没有找到问题的解决方案，但是几天前已经有人问过同样的问题 - (Rails 服务器不断退出 (SocketError))
I have not found a solution to the problem, however someone did already ask about the same problem a few days ago - (Rails Server Keeps Exiting (SocketError))
启动 rails 服务器后，系统返回一些我无法理解的错误.为了在我的 Mac 上安装 Ruby on Rails，我按照 http://railsapps.github 上列出的所有内容进行了操作.io/installrubyonrails-mac.html
After I start a rails server the system returns some error I cannot understand. To install Ruby on Rails on my mac I did everything as listed on http://railsapps.github.io/installrubyonrails-mac.html
这是我的终端回复:
$ rails server
=> Booting WEBrick
=> Rails 4.2.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
[2015-02-28 02:14:46] INFO WEBrick 1.3.1

请帮忙.
推荐答案
问题通过在private/etc/hosts文件中添加127.0.0.1 localhost记录解决，之前因为某种原因被删除了.
The problem solved by adding 127.0.0.1 localhost record to the private/etc/hosts file, which was removed by some reason before.
这篇关于rails 服务器无法启动；getaddrinfo: nodename 或 servname 提供，或未知 (SocketError)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
