Kivy not working (Error: Unable to find any valuable Window provider.)

Question

I have been getting this error: Unable to find any valuable Window provider. With kivy heres the "full" error:

thats the error and heres the code:

import kivy #added this just in case
from kivy.app import App
from kivy.uix.label import Label


class SimpleKivy(App):
    def build(self):
       return Label(text="Hello World!!!")

if __name__ == "__main__":
   SimpleKivy().run()

Can someone explain this error

Answer 1

You're probably missing some dependencies. From the docs:

Install the dependencies (skip gstreamer (~120MB) if not needed, see Kivy’s dependencies):

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew;

python -m pip install kivy.deps.gstreamer

To install these dependencies, open up a terminal (can be a console, Pycharm Terminal window, etc.), run the first command and then the second command.
