python窗体应用程序错误_python – 如何解决Kivy错误：错误窗口(窗口参数无效)？...

我安装了Kivy和Cython.我使用VirtualBox和Arch

Linux与Gnome作为我的显示管理器.创建以下应用程序后,

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()

我收到以下错误

[INFO ] [Logger ] Record log in /home/kyle/.kivy/logs/kivy_17-10-19_40.txt

如果我运行命令unset DISPLAY它按预期工作,但没有选项来最小化,最大化和关闭通常可用的窗口.

有没有办法修复此错误,所以每次打开一个新的终端窗口并让它看起来像普通窗口时,我不需要键入未设置的DISPLAY？
