Fedora 26 中 Python M2Crypto 安装失败

Question

我在我的 PC 上运行 Fedora 26，python 版本是 2.7。我已经安装了

openssl-devel

包。现在我正在尝试安装

M2Crypto==0.25.1

使用命令在python虚拟环境中进行打包

pip install M2Crypto==0.25.1

。安装总是失败并显示以下日志语句。

尝试使用 compat-openssl10-devel:

sudo dnf install compat-openssl10-devel --allowerasing

如果与 open-ssl 冲突，您可能必须删除它。您可以在安装 M2Crypto 后重新安装 open-ssl
