python-3.x - Pip无法安装任何包

Question

您好大约 2 周前，我开始无法下载 python 包，甚至无法访问在 chrome 和 firefox 上“无法访问”的 pypi 网站。

当我尝试下载一个包时，它给了我这个:

$ python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose
Collecting numpy
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))': /simple/numpy/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))': /simple/numpy/

我不知道为什么会发生这种情况，我没有对我的计算机进行任何更改，有一天它才开始在我的两台计算机上执行此操作，我不明白。
有人知道为什么会这样吗？我搜索了几个小时，但找不到任何东西来纠正这个错误。

我尝试过的:
- 卸载每个python程序并重新安装
- 检查我的驱动程序(你永远不知道)
- 停用任何代理
- 禁用我的防火墙

所以对于任何寻找解决方案的人，我发现这可能不是最佳的，但至少它有效，而不是 pip install package 使用这个命令

python.exe -m pip 安装包 --proxy="proxy:port"

您可以在此处找到大量免费代理列表:https://free-proxy-list.net/ (请注意，并非所有这些都有效，您可能想尝试多个，然后再获得一个有效的)

例如，您可以使用:
python.exe -m pip install numpy --proxy="179.185.199.195:8080"

这有效，
