编译错误安装python-igraph：警告视为错误 [英] Compiler error installing python-igraph: Warnings treated as errors

问题描述

尝试使用pip为Python 3安装 python-igraph ，我得到以下编译器错误。我可以改变一些东西，或者这是igraph中的错误吗？注意行 cc1：最后一些警告被视为错误 - 如果它们只是警告，我可以忽略它们吗？

Trying to install python-igraph with pip for Python 3, I get the following compiler error. Can I change something or is this a bug in igraph? Note the line cc1: some warnings being treated as errors in the end - if they are just warnings, can I just ignore them somehow?
