我正在尝试使用pip3在fedora23工作站上安装cffi。
但我得到以下错误。
pip3 install cffi

命令“ python setup.py egg_info”在/ tmp / pip-build-yweqr7c9 / cffi中失败，错误代码为1
我该怎么办？
提前感谢。
最佳答案
正如Tom的评论中指出的那样，在编译cffi之前必须先安装一些依赖项。但是，对于我来说，仅libffi-devel是不够的，还需要redhat-hardened-cc1作为redhat-rpm-config的一部分。您可以使用
sudo dnf install libffi-devel redhat-rpm-config
现在，您可以再次运行
pip3 install cffi，并且应该全部编译。关于python - 无法在fedora23工作站上安装cffi，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/34554599/
