Python 2.7 kartograph未知形状类型（25）

我正在尝试使用kartograph py生成svg地图，如下所示：

from kartograph import Kartograph
K = Kartograph()
config ={"layers": {"mylayer": {"src": "42MEE250GC_SIR.shp"}} }
K.generate(config, outfile='mymap.svg')

我得到一个错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\k

有人能帮我吗

我在下面尝试了这个，但我得到了另一个错误

if shp.shapeType == 25:
  return None

错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\k

计算映射边界的方法

我找到的解决方案是更改源代码，添加以下内容：

if shp.shapeType == 25:
  geom = points2line(shp)

---

我确信这不是最好的解决方案，但它解决了我的问题

mymap.svg不是生成的我错了，我的意思是输入文件是什么？输入文件是从这里获得的巴西州地图：

if shp.shapeType == 25:
  geom = points2line(shp)
