Question

我使用kivy python编写了一个简单的应用程序，但是当我在桌面上运行该应用程序时，它显示了黑屏，我尝试了StackOverflow的所有解决方案，但是它不起作用

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


class Lesson1App(App):
    def build(self):
        lbl = Label(text='Hello World!')
        return lbl


if __name__ == '__main__':
    Lesson1App().run()

这就是我在CMD上显示的内容

尝试像我一样更改您的python-kivy版本。但是首先，如果您没有窗口，也许您遇到大小问题，可以在.py文件路径上尝试以下cmd命令： python。\ main。 py --size = 500x500 -f

猕猴桃输出黑屏
