Question

我试图安装python-igraph。运行sudo pip install python-igraph后，我收到了以下日志：

Downloading/unpacking python-igraph
  Downloading python-igraph-0.7.1-1.tar.gz (375kB): 375kB downloaded

    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.
    Version number of the C core: 0.7.1-1

    Version 0.7.1-1 of the C core of igraph is not found among the nightly builds.
    Use the --c-core-version switch to try a different version.

    Could not download and compile the C core of igraph.

    WARNING: we were not able to detect where igraph is installed on
    your machine (if it is installed at all). We will use the fallback
    library and include pathss hardcoded in setup.py and hope that the
    C core of igraph is installed there.

    If the compilation fails and you are sure that igraph is installed
    on your machine, adjust the following two variables in setup.py
    accordingly and try again:

    - LIBIGRAPH_FALLBACK_INCLUDE_DIRS
    - LIBIGRAPH_FALLBACK_LIBRARY_DIRS

如果我使用sudo python setup.py install进行此操作，情况类似。

显然问题在于C核心。

如何安装正确的版本以便我可以安装igraph？

我使用Linux Mint 16 64位，python 2.7。

Answer 1

在编译python-igraph之前，你需要igraph库。

尝试sudo apt-get install -y libigraph0-dev并尝试再次安装python-igraph。

Answer 2

使用Ubuntu 16和Python3。

pip3 install python-igraph

导致错误构建。但是，

sudo apt-get install python3-igraph

工作得很好。

Answer 3

对于Windows用户

Download非官方python-igraph（根据igraph official installation instruction），请根据环境选择合适的.whl文件（python版本，64位对比32位）。
打开命令控制台，将cd打开到.whl文件夹

执行以下命令：

pip install python_igraph-0.7.1.post.xxx.whl

Answer 4

在Ubuntu 16.04中：

对于python 2：

apt-get install build-essential python-dev libxml2 libxml2-dev zlib1g-dev

对于python 3：

apt-get install build-essential python3-dev libxml2 libxml2-dev zlib1g-dev

解决了我的问题。

Answer 5

对于Ubuntu用户：

将igraph的存储库添加到apt：

sudo add-apt-repository ppa:igraph/ppa

然后更新并安装python-igraph包：

sudo apt-get update
sudo apt-get install python-igraph

未能安装python-igraph
