无法使用Kivy获取窗口或文本提供程序

Question

我对编码和Kivy业务非常陌生。我为自己的无知表示歉意。首先，我认为我的PATH出了点问题。有时，在我使用pip安装模块后，这些模块将永远无法被识别，因此可能是问题所在。最近，我已经从Sublime Text过渡到Visual Studio2019。我已经尝试了Internet上提供的所有教程。我认为问题是我，我不明白自己在做什么。附件是我尝试过的所有建议：

• https://github.com/kivy/kivy/issues/5677

• sdl2 - ImportError: DLL load failed: The specified module could not be found and [CRITICAL] [App] Unable to get a Window, abort

• Kivy error, [CRITICAL] [Text ] unable to find any valuable text provider (python 3.6.1) (windows 10)

• https://www.youtube.com/watch?v=gt-qndBYrCQ&feature=youtu.be

• ImportError: No module named PIL

我现在已经以所有这些不同的配置卸载和安装了Kivy 4或5次。如果我发送任何依赖项以进行下载，我保证它会告诉我它已经满足了。

这里是程序：

import kivy

from kivy.app import App
from kivy.uix.label import Label

class FirstKivy(App):
    def build(self):
        return Label(text="Hello World")

if __name__ == '__main__':
    FirstKivy().run()

这里是Visual Studio给我的错误

感谢您的耐心等待：）

我的项目中有相同的问题，但我解决了。我在项目中安装了[kivy-deps.sdl2]和[kivy-deps.glew]软件包它开始运行。我将PyCharm用于开发工具，并安装了以下过程：

1. 转到[Settings]

2. 选择[Project]和[Project Iterpreter]

3. 使用+ kivy安装软件包添加要运行的软件包：[Kivy],[kivy-deps.sdl2]和[kivy-deps.glew]
