Kivy编程错误

Question

我是新来的.

我在一个hello world程序中遇到了一些错误，我无法理解它。

请帮帮我

代码是

from kivy.app import App

from kivy.uix.label import Label

class test(App):
        def build(self):
                return Label(text="hello world")

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

错误消息是

我使用的是ubuntu 14.10

Answer 1

您的第一个错误是“已忽略(导入错误)”。

你需要安装"python3-pygame“。

然而，Ubuntu的官方存储库没有"python3-pygame“。

例如，请安装以执行此操作。

sudo add-apt-repository ppa:thopiekar/pygame
sudo aptitude update
sudo aptitude install python3-pygame

你一开始有没有进口奇异果？

import kivy
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
