我这里用pycharm安装Kivy(1.11.0)和Cython(0.29.10) ,然后执行以下代码:

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

class TestApp(App):
    def build(self):
        return Button(text="Hello,kivy")
if __name__ == '__main__':
    TestApp().run()

大概报错:

[CRITICAL] Window: Unable to find any valuable Window provider.
 Please enable debug logging (e.g. add -d if running from the command line, 
or change the log level in the config) and re-run your app to 
identify potential causes
sdl2 - ImportError: DLL load failed: 找不到指定的模块。

也就是缺少sdl2模块,在pycharm中安装这个模块:kivy-deps.sdl2,再次执行,又报错:

[DEBUG  ] Window: Ignored <sdl2> (import error)
[CRITICAL] Window: Unable to find any valuable Window provider. Please enable debug logging (e.g. add -d if running from the command line, or change the log level in the config) and re-run your app to identify potential causes
sdl2 - ImportError: DLL load failed: 找不到指定的模块。
  File "D:\develop\study\爬虫\venv\lib\site-packages\kivy\core\__init__.py", line 71, in core_select_lib
    cls = cls()

下载python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew

我这里看了下只缺少最后一个,用pycharm下载安装这个模块:kivy-deps.glew

最后成功。

以上kivy不支持显示中文 ,解决方法(字体随便下个,自己已传网盘):

参考链接:https://blog.csdn/lutong26971/article/details/84647790

from kivy.app import App
# from kivy.uix.button import Button
from kivy.uix.label import Label

class TestApp(App):
    def build(self):
        return Label(text="这里可以写中文了", font_name='font.TTF')  # font_name里写入字体所在路径
if __name__ == '__main__':
    TestApp().run()
