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进行操作。首先我做了./configure，然后make，然后进行测试。

当我运行make test时出现错误，我不知道为什么，我只是按照指示完全按照说明进行操作。这是输出：

test test_smtpnet failed -- Traceback (most recent call last):

所以似乎_socket模块尝试使用协议不支持的“地址族”（无论是什么）。这个例外可以更模糊吗？

有人知道我在这里缺少什么吗？

看起来测试用例确实需要启用IPv6。因此，在未启用IPv6支持的系统上将失败。检查ip a s的输出以查看VM是否具有IPv6地址集，例如通常以fe80::开头。地址族可以是IPv4的AF_INET或IPv6的AF_INET6。实际上，这是一个测试用例错误。

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