Question

我正在使用Windows 7虚拟机，但是无法添加ctypes。我的物理机运行Ubuntu，互联网连接是一个WiFi热点。

发生错误：

无法获取网址https://pypi.org/simple/ctypes/：存在一个确认ssl证书时出现问题： HTTPSConnectionPool（host ='pypi.org'，port = 443）：超过最大重试次数网址：/ simple / ctypes /（由SSLError（SSLError（1，'_ssl.c：499：错误：1407742E：SSL例程：SSL23_GET_SERVER_HELLO：tlsv1警报协议版本'），））-跳过

命令输出：

Answer 1

尝试升级您的urllib安全软件包，例如通过点子。

pip install urllib3[secure]

这应该指导您： https://urllib3.readthedocs.io/en/latest/user-guide.html#ssl-py2

您的urllib似乎尝试使用tlsv1访问pypi。很可能他们不再允许您了。

使您的工具链保持最新状态，您应该会很好。
