安装kivy库第一次使用出现问题

Question

按照教程安装了依赖和kivy库都没有出现问题

第一次使用如下代码

from kivy.app import App
from kivy.uix.button import Button
class TestApp(App):
    def build(self):
        return Button(text='iPaoMi')
TestApp().run()

然后运行结果显示错误

该怎么办？

Answer 1

试试执行下面的代码

pip install --upgrade pip wheel setuptools
pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
pip install kivy.deps.gstreamer
pip install kivy.deps.angle
