python - pip raises ProtocolError('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

Question

当我使用 pip 安装软件包时，由于 ProtocolError，所有安装都失败了。我的 python 和 pip 是由 pyenv 安装的。这是错误消息：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))': /simple/requests/

ERROR: Could not find a version that satisfies the requirement requests (from versions: none)

这是详细模式打开的消息：

该错误似乎是 urllib3 错误，并且缺少某些内容。关于缺少什么的任何想法？欣赏任何信息！

仅供参考，我已尝试重新安装 python，但它仍然无法正常工作。我也尝试了由 anaconda 安装的 python，但它的 pip 也不起作用。只有系统内置的 pip 有效。
