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()
