Question

[Saharman]

Сделал простое приложение, которое просто создает кнопку. Запустил. Получил следующую ошибку:

Если сильно важно, вот код программы:

import kivy
from kivy.app import App
from kivy.uix.button import Button

class CalcApp(App):
    def build(self):
        return Button(text='Hello,world!')


if __name__=='__main__':
    CalcApp().run()

Вот такая проблема;

The directory '/home/nafanya/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

      This version of Cython is untested with Kivy. While this version may
      work perfectly fine, it is possible that you may experience issues. If
      you do have issues, please downgrade to a supported version. It is
      best to use the newest supported version, 0.25.2, but the minimum
      supported version is 0.23.
    
      If your platform provides a Cython package, check if you can downgrade
      to a supported version. Otherwise, uninstall the platform package and
      install Cython via pip:

pip install -I Cython==0.25.2

[Saharman]

Web Dentist, я его установил, до этого выдало ошибку, что не cython. решилось все там, что установил из apt-get kivy.
