所以，我修修补补与Kivy位，但我不能使它工作，我只想能够启动一个屏幕现在，但我无法做到这一点.我不知道如果代码我一直在网上看到的是坏的，或者如果有一个错误或我做了一些错误的安装时. PS：我用的是Windows和PyCharm。
我已经多次尝试卸载和重新安装Kivy、PIL和Pillow，在app.py中写入import PIL和Pillow。

import os
import kivy
from kivy.app import App
from kivy.uix.label import Label

class MyApp(App):
    def build(self):
        return Label(text="Hello")

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

这是它给我的错误：
