我正在使用nokogiri，我正在收到此错误
Failed to open TCP connection to 127.0.0.1:41585 (Connection refused - connect(2) for "127.0.0.1" port 41585)
在代码的这一行上
doc = Nokogiri::HTML(open('https://www.instagram.com/p/BfaMpSuDTbn/'))
我应该提到，我最近在注册红宝石的情况下运行了一个许可证，并且可能已更改了系统设置。

有什么想法？
实际上是因为我用于注册Rubymine的许可证服务器。重新安装导轨解决了问题。
错误代码明确表示您的连接被拒绝。这意味着，服务器不允许您访问Ressource。
