为 igraph 安装 pycairo 有什么问题？

我按照此处的说明要在 win 上安装 pycairo 并能够在 igraph 中使用绘图，

我有 python 2.7 pycairo 1.8.10

和上面链接中写入的具有相同编号的 dll 文件，然后我使用了编写的测试，但收到了消息：

from igraph import *    
g = Graph.Famous("petersen")
plot(g)

发生错误导致照片或视频无法显示。错误代码：0x800706ba

在尝试保存到文件时，我也收到以下错误。

from igraph import *    
g = Graph.Famous("petersen")
plot(g, "test.png")

这给出了以下错误：

回溯（最近一次调用最后一次）：文件“”，第 1 行，位于
文件“C:\Program Files (x86)\Python27\lib\site-packages\igraph\drawing__init__.py”，第 438 行，在图中
结果.save()
文件“C:\Program Files (x86)\Python27\lib\site-packages\igraph\drawing__init__.py”，第 299 行，保存
返回 self._surface.write_to_png(fname)
IOError：写入输出流时出错

为什么这不起作用？

原文

I followed the instructions here
to install pycairo on win and be able to use plotting in igraph

I have python 2.7
pycairo 1.8.10

and dll files with the same numbers written in the above link, then I used the test written but I got the message:

from igraph import *    
g = Graph.Famous("petersen")
plot(g)

An error is preventing the photo or video from being displayed.
Error code: 0x800706ba

I also get the following error when trying to save to a file.

from igraph import *    
g = Graph.Famous("petersen")
plot(g, "test.png")

Which gives the following error:

Traceback (most recent call last):
File "", line 1, in
File "C:\Program Files (x86)\Python27\lib\site-packages\igraph\drawing__init__.py", line 438, in plot
result.save()
File "C:\Program Files (x86)\Python27\lib\site-packages\igraph\drawing__init__.py", line 299, in save
return self._surface.write_to_png(fname)
IOError: error while writing to output stream

Why is this not working?
