python - 无法在 Kivy 中导入 MapView

Question

进口：

from kivy.app import App      
from kivy.garden.mapview import MapView, MapMarker

class MapViewApp(App):
    def build(self):
        map = MapView(zoom=11, lat=50.6394, lon=3.057, double_tap_zoom = True)
        marker_1 = MapMarker(lon=50.6394, lat=3.057)
        map.add_marker(marker_1)
        return map

MapViewApp().run()

错误：

from kivy.garden.mapview import MapView, MapMarker
File "<frozen importlib._bootstrap>", line 1007, in _find_and_load
File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked
File "<frozen importlib._bootstrap>", line 664, in _load_unlocked
File "<frozen importlib._bootstrap>", line 635, in _load_backward_compatible
KeyError: 'kivy.garden.mapview'
[Finished in 0.4s with exit code 1]

我安装了那个

pip install mapview
