use IO::Socket::SSL 'inet4';

对我来说很有用。它到底在哪里失败了？错误消息来自构造函数吗？是的，Mail:：IMAPClient->new（）在此失败，本主题的标题是错误消息“IO:：Socket:：SSL:connect:Network Is unreachable”“'Network unreachable'与Perl或SSL无关。这是一个网络拓扑问题。但是”telnet imap.gmail.com 993“运行正常，ping和NSLookupple也添加了echo-n | openssl s|u client-connect imap.gmail.com:993Hmm。总之，我可以很好地运行您提供的脚本。您使用什么perl和操作系统？感谢CentOS 6上的@MichielB.perl v5.10.1（64位）。可以在相同的环境中运行代码。您的网络是什么样子的？您有支持IPv6的NIC吗？您有支持IPv6的网络吗？对我也很有用！干杯！
use IO::Socket::SSL 'inet4';
