使用python for android将kivy应用程序编译为apk失败

我用python和kivy编写了一个hello world测试应用程序，并尝试将其打包到apk中，但它一直向我显示这个错误，我不明白发生了什么

这是我的代码：

import kivy
kivy.require('1.11.1')

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

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

if __name__ in ('__android__', '__main__'):
    MyApp().run() 

我尝试使用以下命令编译为apk：

p4a apk --private ./ --package=org.example.easample --name "easample" --version 0.1 --bootstrap=sdl2 --requirements=python3,kivy,pygame

它给出了以下错误消息：

请告诉我需要帮助

你试过在Ubuntu中使用Buildozer吗？没有。我现在就来试试。你用什么操作系统来编译。不要用pygame，把它从要求中去掉。我用的是ubuntu@我现在就把它拿出来。你试过在Ubuntu中使用Buildozer吗？没有。我现在就来试试。你用什么操作系统来编译。不要用pygame，把它从要求中去掉。我用的是ubuntu@我现在就把它拿出来
