由于SSL，Pycharm安装包失败

Question

我使用Windows 7虚拟机，我不能添加ctype。我的物理机器运行Ubuntu，互联网连接是无线热点。

错误发生：

无法获取URLhttps://pypi.org/simple/ctypes/:确认ssl证书时出现问题：HTTPSConnectionPool（host='pypi.org'，port=443）：url:/simple/ctypes超过了最大重试次数/（由SSLError（SSLError（1'，ssl.c:499:error:1407742E:ssl例程：SSL23\u GET\u SERVER\u HELLO:tlsv1警报协议版本'）引起）-跳过

命令输出：

Answer 1

尝试升级你的urllib安全包，例如通过pip。

pip install urllib3[secure]

这将指导您：https://urllib3.readthedocs.io/en/latest/user-guide.html#ssl-py2

您的urllib似乎试图通过tlsv1访问pypi。很可能他们不再允许你这么做了。

让你的工具链更新，你会没事的。
