问题描述

任何人都知道如何使用kivy吗?我在python2.7的window7上安装了它.当我运行以下代码时:

Anyone know how to use kivy? I installed it on my window7, python2.7. When I run following code:

import kivy

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


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

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

它给出以下错误:

无法获取窗口，请中止.

Unable to get a Window, abort.

我在python3.4上尝试过，出现同样的错误.有人知道如何解决这个问题吗?拜托.

I tried on python3.4, same error. Anyone know how to solve this problem? Please.

推荐答案

有一个选项，sdl2找不到加载* .png所需的dll

There is an option that sdl2 can't find dlls needed to load *.png

• 尝试找到libpng16-16.dll

在这里:C:\Python27\share\gstreamer\bin

• 将其添加到PATH

• Add it to PATH

set PATH=C:\Python27\share\gstreamer\bin;%PATH%

这是临时解决方案，但对我有用

This is temporary solution but it works for me
