Question

我正在尝试使用pip3在fedora23工作站上安装cffi。但是我得到了以下错误。

pip3 install cffi

Collecting cffi

Complete output from command python setup.py egg_info:

命令“python setup.py egg_info”失败，错误代码1在/ tmp / pip-build-yweqr7c9 / cffi

我该怎么办？提前谢谢。

正如Tom的评论所指出的那样，在编译cffi之前必须先安装一些依赖项。但是，在我的情况下仅libffi-devel还不够，还需要使用redhat-hardened-cc1作为redhat-rpm-config的一部分。您可以使用

安装它们

sudo dnf install libffi-devel redhat-rpm-config

现在你可以再次运行pip3 install cffi，它应该全部编译。
