Question

我在PC上运行Fedora 26，python版本是2.7。我已经安装了

的openssl-devel的

包。现在我正在尝试安装

M2Crypto == 0.25.1

使用命令

在python虚拟环境中打包

pip install M2Crypto == 0.25.1

。安装始终失败，并显示以下日志语句。

尝试使用compat-openssl10-devel：

sudo dnf install compat-openssl10-devel --allowerasing

如果与它发生冲突，您可能必须删除open-ssl。安装M2Crypto后可以重新安装open-ssl
