[英]rails server cannot start; getaddrinfo: nodename nor servname provided, or not known (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) ) 我还没有找到问题的解决方案,但是几天前有人已经问过同样的问题了 - ( Rails Server Keeps Exiting(SocketError) )
After I start a rails server the system returns some error I cannot understand. 启动rails服务器后,系统返回一些我无法理解的错误。 To install Ruby on Rails on my mac I did everything as listed on http://railsapps.github.io/installrubyonrails-mac.html
要在我的Mac上安装Ruby on Rails,我做了http://railsapps.github.io/installrubyonrails-mac.html上列出的所有内容。
here is my terminal response: 这是我的终端回复:
$ rails server

=> 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
文件解决了该问题,该文件之前由于某种原因被删除。
Try changing to UNIX Encoding: 尝试更改为UNIX编码:
brew install dos2unix
sudo dos2unix -c mac /private/etc/hosts
I had a similar problem with Redis in a rails environment. 我在rails环境中遇到类似Redis的问题。 I added the port number and "Redis" to my /private/etc/hosts file on my mac, and it solved the error.
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。 Say your port number is "1234", you would add: 1234 redis.
假设您的端口号为“1234”,您可以添加:1234 redis。 In the case of localhost, you would add: 127.0.0.1 localhost.
对于localhost,您将添加:127.0.0.1 localhost。 I hope this provides at least some clues to your particular issue.
我希望这至少能为你的特定问题提供一些线索。
For any future users who run into this issue I was able to solve it by adding the following at the end of my private/etc/hosts
file. 对于遇到此问题的任何未来用户,我可以通过在我的
private/etc/hosts
文件末尾添加以下内容来解决此问题。
127.0.0.1 YOURNAME-MacBook-Pro.local
Update YOURNAME-MacBook-Pro
to whatever the name of your machine is and hopefully you'll be all set. 将
YOURNAME-MacBook-Pro
更新为您机器的任何名称,并希望您将全部设置好。
