「Polygone」對象不支持索引

我想使用Kartograph.py呈現SVG地圖。它引發了TypeError。下面是Python代碼：「Polygone」對象不支持索引

import kartograph 
from kartograph import Kartograph 
import sys 
from kartograph.options import read_map_config 
css = open("stylesheet.css").read() 
K = Kartograph() 
cfg = read_map_config(open("config.json")) 
K.generate(cfg, outfile='dd.svg', format='svg', stylesheet=css)

下面是它拋出

Traceback (most recent call last): 
    File "<pyshell#33>", line 1, in <module> 
    K.generate(cfg, outfile='dd.svg', format='svg', stylesheet=css)

    N = len(ob[0][0][0]) 
TypeError: 'Polygon' object does not support indexing

您可以添加「config.json」文件的內容嗎？ – cchristelis

我看了一下身材勻稱，它看起來像您使用的是過時的版本錯誤。更新您的當前安裝：

pip install -U shapely
