Error when running kivy on python

[janeik]

The error says it cannot find a module named "kivymd". Did you install kivymd? Installing kivy does not install kivymd.

When you type "pip list" in a command shell, does it list kivymd?

I tried to change code to:
[python][


from kivymd.app import MDApp
from kivy_garden.mapview import MapView


class MyApp(MDApp):

def build(self):
mapview = MapView(zoom=10, Lat=36, Lon=-115)
return mapview
MyApp().run()
/python]

Got this error:
