get_adm_maps(city='四平市', level='市', only_polygon=True, record='first') + get_adm_maps(city='长春市', level='市', only_polygon=True, record='first')
<cnmaps.maps.MapPolygon object at 0x17ef11b80>

看起来可能是吉林的问题,我用四平+吉林也汇报同样的错,四平+长春就可以。

get_adm_maps(city='吉林市', level='市', only_polygon=True, record='first') + get_adm_maps(city='辽源市', level='市', only_polygon=True, record='first')

吉林市可能数据源有问题,但是我不知道这个应该怎么找问题了。

修改maps.py的69行为:

                try:
                    polygons.remove(other)
                except ValueError:
                    continue

可以解决问题,估计还是边界的数据有问题。
代码洁癖不知道是否可以接受try的结构。
或者可以改为if之类的结构。
