有谁知道为什么Python的2.7 Spyder只是成功初始化'Hello World'Kivy应用程序一次,即点击F5会带来窗口应用程序,但当我关闭它并再次点击F5时,它会显示以下错误:

[INFO              ] [Base        ] Start application main loop
[ERROR             ] [Base        ] No event listeners have been created
[ERROR             ] [Base        ] Application will leave

但是,通过Anacondas命令提示符初始化时没有错误.

这是代码(与网站相同):

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

class TestApp(App):
    def build(self):
        return Button(text='Hello World')

TestApp().run()

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