Python 3.4.1 make test失败：错误：test_connect_starttls（test.test_smtpnet.SmtpTest）

Question

我刚刚在我的centos 6.4虚拟机上下载了python 3.4.1，并按照自述文件中的说明操作。首先我做了./configure，然后make，然后做测试。

当我运行make测试时出现错误，我不知道为什么，我只是按照指示完全按照指示进行操作。这里是输出：

因此它似乎使用“地址族”（不管到底是）试过_socket模块不受该协议的支持。这个例外可能会更模糊吗？

有人知道我在这里失踪了吗？

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，它将会失败。检查ip a s的输出以查看虚拟机是否设置了IPv6地址，例如通常从fe80::开始。地址族可以是IPv4的AF_INET或IPv6的AF_INET6。其实，这是一个测试用例错误。
