python之AttributeError: module ‘pygal‘ has no attribute ‘Worldmap‘

代码块替换成为了：pygal_maps_world.maps

在pygal_maps_world.maps.World(),对世界地图进行调用

import pygal_maps_world.maps

wm = pygal_maps_world.maps.World()
wm.title = "NOrth,Centeal,and South America"

wm.add('North America',['ca','mx','us'])
wm.add('Central America',['bz','cr','gt','hn','ni','pa','sv'])
wm.add('South America',['ar','bo','br','cl','co','ec','gf','gy','pe','py','sr',
                        'uy','ve'])
wm.render_to_file('americas.svg')
