我在 linux 环境中使用 python 3.10.8（RedHat 7.9 Maipo）。在使用所有库手动安装 python 3.10.8 后，我遇到了这个错误：

我在这里的其他帖子中看到过，但没有找到解决方案。我也安装了openssl。

> [root@epnm-lab-02-ha-01 ~]# rpm -qa|grep ^openssl*
> openssl-1.0.2k-21.el7_9.x86_64 
> openssl-libs-1.0.2k-21.el7_9.x86_64

这有什么问题吗？谁能帮我解决这个问题？

【问题讨论】：

也许它还需要 Python 模块pyOpenSSL
@furas For pyOpenSSL 只是安装？
在 Linux Mint 上，我只安装了 pyOpenSSL 和 openssl，但我从 Linux Mint/Ubuntu 的特殊仓库安装了 python3.10。也许它可能需要将一些文件.so 复制到带有urllib 的文件夹中
我将尝试安装 pyOpenSSL。尽快给您反馈。谢谢，我的朋友
我已经安装了pyOpenSSL，但它没有用。还有什么建议吗？

【解决方案1】：

解决了！

这个错误的解决方法是python 3.10版使用openssl 1.1.1版，而我的服务器使用的是openssl 1.0.2。 python 3.10 上的 openssl 版本 1.0.2 已被弃用。所以你需要安装python 3.9.x，因为这个版本支持openssl 1.0.2。

希望有帮助！
