我还没有找到问题的解决方案,但有几天前有人已经问过同样的问题 - (Rails Server Keeps Exiting (SocketError))
启动rails服务器后,系统会返回一些我无法理解的错误。要在我的Mac上安装Ruby on Rails,我执行了http://railsapps.github.io/installrubyonrails-mac.html
上列出的所有操作这是我的终端回复:
$ 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

通过将127.0.0.1 localhost
记录添加到private/etc/hosts
文件来解决问题,该文件之前因某种原因被删除了。

我在rails环境中遇到类似Redis的问题。我将端口号和“Redis”添加到我的mac上的/ private / etc / hosts文件中,它解决了错误。假设您的端口号为“1234”,您可以添加:1234 redis。对于localhost,您将添加:127.0.0.1 localhost。我希望这至少能为你的特定问题提供一些线索。

对于遇到此问题的任何未来用户,我可以通过在private/etc/hosts
文件的末尾添加以下内容来解决此问题。
127.0.0.1 YOURNAME-MacBook-Pro.local
将YOURNAME-MacBook-Pro
更新为您的计算机名称,并希望您将全部设置。
