python - 用anaconda2 pip安装python-igraph，找不到C核心。 Linux Fedora 24

Question

我想从 Anaconda 4.1.1 安装 igraph for python 2.7.12 我有 Fedora 24。按照建议(https://anaconda.org/pypi/python-igraph)我使用了这个命令行:

pip install -i https://pypi.anaconda.org/pypi/simple python-igraph

输出包括这些行:

[...]

Cannot find the C core of igraph on this system using pkg-config.
  We will now try to download and compile the C core from scratch.

然而，当我检查我是否有 gcc 时，我得到:

dnf install gcc
Last metadata expiration check: 1:16:49 ago on Fri Jul 15 09:02:56 2016.
Package gcc-6.1.1-3.fc24.x86_64 is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!

从 igraph 网页说:

if the C core is not installed or is installed in a location that cannot be detected using pkg-config, pip will attempt to download a matching version of the C core and compile it together with the Python interface.

所以我猜 pip 尝试下载 C 核心但不能/没有工作。

如何正确安装 python-igraph？

提前致谢。

checking for g++... no

安装 g++ : # dnf install gcc-c++

igraph 库、igraph_attributes.h 等 headers.h :# dnf install igraph-devel(您获得版本 0.7.1)。

python 文件:

# pip install --upgrade pip
# pip install igraph
