PIP 无法在我的 Rasberry Pi (Raspbian) 上运行，引发 ssl 错误

Question

当我尝试在我的 Raspberry-Pi（运行 Raspbian Buster）上使用 pip 安装 python 包时，出现以下错误：

pip install opencv-python (same for every other package)

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting opencv-python

  ... (repeatedly same error message with total=x changing)

  Could not find a version that satisfies the requirement opencv-python (from versions: )

我在我的 Windows 机器上尝试了同样的命令，它按预期工作。我已经尝试添加各种受信任主机参数和其他网站上人们建议的参数，但没有任何变化。
