安装 Python 库时如何修复 Python SSL 证书错误？

Question

我在 Python 中安装软件包时遇到问题。几天前才开始 - 程序运行良好，但每当我尝试运行 pip install Pillow 或 pip install pygame（一直在测试各种图形库）我总是运行陷入同样的错误。

Collecting pygame

我试过升级 pip、降级 pip、安装新版本的 Python，并且我尝试了安装命令的各种变体以使其正常工作。 尝试升级证书将错误更改为此。

我在网上找到的解决方案似乎是面向 Mac 的，我正在运行 Windows。我不明白问题发生在哪里，因为 Python 程序运行得非常好（我在 VSC 和 PyCharm 上都试过了，还有似乎没有任何问题）。 我怎么go解决这个问题？

我不知道具体情况，但你可以试试

pip install pip-system-certs
