UnicodeDecodeError安装时python-igraph

Question

我在64位Linux Mint 16上使用python 2.7，我试图安装python-igraph。但是，当我运行sudo pip install python-igraph我得到以下日志：

我以前安装libigraph0-dev的。我如何在这种情况下安装python-igraph？

Answer 1

libigraph0-dev的版本是否与Python接口的版本号相匹配？如果libigraph0-dev的版本不等于0.7.1，则它将不适用于您试图编译的版本python-igraph。在这种情况下，最好删除libigraph0和libigraph0-dev并再次运行pip install python-igraph;安装脚本将尝试首先下载并编译适当版本的igraph C核。

我知道您今天发布了另一个问题，其中您指出pip install python-igraph（没有libigraph0-dev）不适用于您;无论如何再试一次，因为python-igraph的前一个版本有一个错误，导致它无法下载正确版本的C核心，并且我在一个小时前修复了这个错误。使用下面的代码的igraph in C

Answer 2

下载源代码，并安装它

./configure && make && sudo make install 

然后使用PIP或从源
