python3.4.1 make test失败：错误：test_connect_starttls(测试测试.SmtpTest（测试）

Question

我刚刚在centos 6.4虚拟机上下载了Python3.4.1，并按照自述文件中的说明进行了操作。首先我做了./configure，然后make，然后make test。在

当我运行maketest时，它出现了一个错误，我不知道为什么，我只是完全按照指令进行操作。输出如下：

因此，似乎∗socket模块尝试使用协议不支持的“地址族”（不管是什么玩意儿）。这个例外可以再含糊一点吗？在

有人知道我在这里遗漏了什么吗？在

看起来测试用例确实需要启用IPv6。因此，在未启用IPv6支持的系统上，它将失败。检查ip a s的输出，查看VM是否有IPv6地址集，例如通常以fe80::开头。对于IPv4系列，IPv4地址可以是IPv4或inetaf。 实际上，这是一个测试用例错误。在
