Python igraph无法绘制 [英] Python igraph unable to plot

问题描述

我想用igraph执行一个简单的绘图，但是出现以下错误:

I wanted to perform a simple plot with igraph but i get the following error:

File "testigraph.py", line 51, in <module>
plot(g, **visual_style)
File "/Library/Python/2.7/site-packages/igraph/drawing/__init__.py", line 446, in plot
result = Plot(target, bbox, background=kwds.get("background", "white"))
File "/Library/Python/2.7/site-packages/igraph/drawing/__init__.py", line 117, in __init__
self._surface_was_created = not isinstance(target, cairo.Surface)
File "/Library/Python/2.7/site-packages/igraph/drawing/utils.py", line 396, in __getattr__
raise TypeError("plotting not available")

看起来像这样的错误 python + igraph无法绘制" ，但是我仍然无法解决我的问题.我尝试按照 http://igraph.org/python上的开罗安装说明进行操作/doc/tutorial/install.html#installing-igraph ，但我不知道如何使它正常工作.

It looks like this error python + igraph "plotting not available" but I still cannot fix my problem. I tried following Cairo install instructions on http://igraph.org/python/doc/tutorial/install.html#installing-igraph but i dont see how to get it working.

现在我收到此错误:

OSError: dlopen() failed to load a library: cairo / cairo-2

我找到了此解决方案安装后无法运行WeasyPrint El Capitan(OSX 10.11)，但不适用于OS X Yosemite.正在运行

推荐答案

这里有同样的问题！我尝试安装pycairo，py2cairo.安装似乎还可以，但是然后:

Same problem here ! I tried to install pycairo, py2cairo. The installation seemed to be okay but then:

1. 我无法导入pycairo
2. igraph的图不起作用

以下内容解决了igraph绘图问题:

The following solved the igraph plotting issue:

sudo pip install cairocffi

因此，我使用的是 cairocffi ，而不是pycairo.

So instead of pycairo I used cairocffi.
