我正在尝试安装 python-igraph。在我运行 sudo pip install python-igraph 之后，我得到了以下日志:

    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:

如果我使用 sudo python setup.py install 执行此操作，我也会遇到类似的情况。

显然问题出在 C 内核上。

如何安装它的正确版本以便我可以安装 igraph？

我使用 Linux Mint 16 64 位，python 2.7。

最佳答案

在编译 python-igraph 之前你需要 igraph 库。

尝试 sudo apt-get install -y libigraph0-dev 并再次尝试安装 python-igraph。

关于linux - 无法安装 python-igraph，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28435418/
