Ruby Net :: OpenTimeout:执行过期

Question

我一直在我的机器上的几台主机上收到此错误,例如:

require 'open-uri'
open('https://google.com').read

不会发生在其他人身上

来自rbenv和macOS 10.12.3的Ruby 2.4.0.还测试了Ruby 2.0.0 - macOS上的系统版本.

当我curl或使用Node 时,我没有得到任何错误和预期的结果request.所以这不是被阻止的主机,我的IP也没有被阻止.

试图重新安装Ruby,重启机器,问题仍然发生.

有什么指针吗？

看起来这是Ruby解析DNS的一个问题.

添加require 'resolv-replace',现在它立即打开连接.
