Ciao a tutti!
Ho un problema con kivi che proprio non ha nessuna intenzione di funzionare!

Scrivo un semplice codice come questo:

from kivy.app import App

from kivy.uix.button import Button

class PrimaApp(App):

    def build(self):

        return Button(text='Hello World')

PrimaApp().run()

ma ottengo questo errore:

Ho trovato su internet molti che hanno avuto lo stesso problema ma tutte le soluzioni suggerite a me non hanno funzionato: qualcuno può aiutarmi?!?

Ho già provato a disinstallare tutto e installare nuovamente...ma niente!

Grazie a chi potrà aiutarmi!

Tiziano

ciao,
sei sicuro di avere installato tutto correttamente? magari prova a disinstallare kivy e reinstallarlo

controlla anche che nella cartella in cui è installato kivy siano presenti i DLL di SDL, ma che non ce ne sia più di uno dello stesso tipo (ad esempio, due SDL2.dll)

Ho già provato a disinstallare e reinstallare sia Python che Kivy...ma continua a non funzionare.
Allego la cartella bin di sdl2...
