openssl - OpenSSL 安装后 Python 3 SSL 失败

问题描述

每当我在安装 openssl 后尝试运行我的 discord.py discord 机器人时，我都会收到这个巨大的错误，据我所知，它的要点是它找不到 Discord 的证书。我用 Bash 和 C++ 进行了测试，它们连接良好，但是我无法通过 python 连接到任何服务器。我已经重新安装了 Certifi 和 CA 证书，以及安装 PyOpenSSL 并手动添加签名密钥。可能是什么问题，我该如何解决？

The above exception was the direct cause of the following exception:

解决方案

这个问题可能是因为你有一个新的 VPS。

我发现最好的解决方法是运行 pip install certifi （确保您使用正确版本的 Python 进行 pip，有时可能是 pip3）

然后当你完成后运行： sudo update-ca-certificates

如果您想知道certifi是什么，它是一个预先安装了请求的软件包，所以如果您有一个新的 VPS，它就没有安装。它是一次性软件包，因此在安装完成后，您应该永远拥有必要的证书。如果你想自己检查它是什么，这里是GitHub 存储库certifi和PyPi 项目certifi

祝你有美好的一天，快乐的编码^^
