когда я попытался установить toga с помощью pip install toga, он установился, но выдал мне ошибку:

мой код на python:

 import toga


class Freedom(toga.App):
    def startup(self):
        self.main_window = toga.MainWindow(self.name)
        self.main_window.app = self

        box = toga.Box()

        self.main_window.content = box
        self.main_window.show()


def main():
    return Freedom('Freedom Units', 'org.pybee.freedom')

if __name__ == '__main__':
    main()
  

но когда я запускаю свой код, он выдает мне это:

 Traceback (most recent call last):
  File "c:projectsappseclipsetempCodeRunnerFile.py", line 19, in <module>    
main()
  File "c:projectsappseclipsetempCodeRunnerFile.py", line 16, in main
    return Freedom('Freedom Units', 'org.pybee.freedom')  File

packagestogaplatform.py", line 42, in get_platform_factory
    from toga_winforms import factoryModuleNotFoundError: No module named 
'toga_winforms'
  

затем я попытался установить toga_winforms с помощью pip install toga_Winforms
но это выдало мне ту же первую ошибку, я пытался искать решения, но ничего не получил.
приветствуется любая помощь.
