我想使用python笔记本，igraph包来画图，示例代码在这里（我认为是对的）
!pip install cairocffi
import cairocffi as cairo
corlor = []
for i in g.vs['name']:
if set([i]) < set(degree_15):
corlor.append('red')
elif set([i]) < set(degree_30):
corlor.append('rgba(255,0,0,0.5)')
elif set([i]) < set(degree_60):
corlor.append('orange')
else:
corlor.append('yellow')
ig.plot(g,
#'C:\Users\Vincent Du\Desktop\degree_plot.jpg',
layout=geometry_layout,
vertex_label=g.vs['name'],
scale=1.0,
vertex_color=corlor,
vertex_frame_width=0.5,
edge_width=0.05,
vertex_label_size=ig.rescale(g.degree(),out_range=(1,12)),
vertex_size=ig.rescale(g.degree(),out_range=(5,25)),
bbox=(1200,800),
margin = 10,
)
而且仍然有一个错误。我不知道如何解决这个问题，谢谢！

我想我已经安装了 cairo，但它仍然无法工作
