更新 Python3 pip AttributeError 时出错：模块“lib”没有属性“OpenSSL_add_all_algorithms”

Question

更新 Python3 pip AttributeError 时出错：模块“lib”没有属性“OpenSSL_add_all_algorithms”

我在 python3 中安装/更新任何 pip 模块时遇到错误。清除并重新安装pip以及我能找到的每个软件包都没有帮助。这是我在响应特定运行时收到的错误python -m pip install --upgrade pip（但尝试安装或更新任何 pip 模块时的错误是相同的）：

我在 WSL 中运行 Ubuntu 20.04。Pythonopenssl已经安装。

我的假设是我需要重新安装一些东西，但我不确定是什么。我已经尝试过一些明显的东西，例如python3-openssl、libssl-dev、libffi-dev和python3-pip它本身以及python3所有这些。

由于版本39.0.0出现了此错误，降级cryptography软件包可以解决此问题，而无需清除或触及您的操作系统。

pip install cryptography==38.0.4降级39.0.0出现此错误的位置

编辑@thomas，

该错误是由于cryptography和之间不兼容造成的pyopenssl，因此如果可能的话，升级到也openssl>22.1.0应该可以工作：

pip install -U pyopenssl cryptography

更具体地说，这似乎是“cryptography”和“pyopenssl”之间的不兼容，如此处所述：https://github.com/pyca/cryptography/issues/7959。降级前者是可行的，但最好将 openssl 升级到 `>22.1.0` （如果不与其他依赖项版本冲突）。 (9认同)
升级两者：`python3 -m pip install -U pyOpenSSL cryptography` (9认同)
pip 命令本身不起作用，如何降级加密？抛出与提到的相同的错误消息。 (3认同)

另一个解决方案是简单地 pip 删除 pyOpenSSL，然后再次安装：

pip uninstall pyOpenSSL
pip install pyOpenSSL
