如何处理 Python 3.8 中的 Kivy 安装错误?

Question

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：

我使用窗口 10，请帮忙！

Answer 1

这对我有用：

马塔姆在15天前评论道 我们不太可能将 3.8 的 1.11.1 版本发布到 pypi。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

适用于Windows 10 Pro和Python 3.8.3

我用这段代码测试它：

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()

Answer 3

这适用于macOS Catalina 10.15.6和python 3.8.0+

pip install kivy==2.0.0rc2

Answer 4

如果您使用的是 conda 环境：

conda install -c conda-forge kivy 

适用于 Python 3.8

Answer 5

我是 windows 10，带有 3.8.2

似乎点安装 kivy==2.0.0rc2 有效。至少它安装了。

是时候判断我是否可以使用 3.8.2 使用它进行开发了
