我刚安装了anaconda和jupyter笔记本。我用pip安装了igraph，但是当我尝试导入时，我得到的定义错误类似于这里提到的错误ImportError igraph: undefined symbol。然后我从github下载了C core并安装了它。在此之后我用pip卸载了igraph并尝试再次安装它，但是我收到以下错误：
pip install python-igraph/

我正在使用ubuntu，conda版本conda 4.2.9和pip infor是： 来自/home/user/anaconda2/lib/python2.7/site-packages(python 2.7）的pip 8.1.2
答案 0 :(得分：2)
这是您安装的C核心或Python安装程序已下载的C核心版本与Python接口版本之间的版本不匹配。从您的机器中删除与igraph相关的所有内容，以确保您从一个干净的平板开始，然后只需运行/home/user/anaconda2/bin/pip install python-igraph。这将从igraph主页下载匹配的C核，并静态链接到Python接口。
