如何处理 Python 3.8 中的 Kivy 安装错误？

我已经从 Kivy 在 Python 中安装了所有必要的代码，但是我需要的最后一个是python -m pip install kivy给我一个这样的错误：

我用的是windows 10，请帮忙！

Answer 1

这对我有用：

马瑟姆 15 天前评论 我们不太可能发布 3.8 到 pypi 的 1.11.1 版本。但是，您可以使用以下命令安装 kivy master：

pip install kivy[base] kivy_examples --pre --extra-index-url https://kivy.org/downloads/simple/

Answer 2

尝试使用pip install kivy==2.0.0rc2或pip install kivy==2.0.0rc1

命令： pip install kivy==2.0.0rc2

与Windows 10 Pro和一起工作Python 3.8.3

我用这个代码测试它：

from kivy.app import App
from kivy.uix.button import Button
 
class TestApp(App):
    def build(self):
        return Button(text= " Hello Kivy World ")

TestApp().run()
