在Python上使用Kivy时，DLL加载失败

Question

I was trying to execute some gui with Kivy and this is what is shows me!

[INFO              ] [Logger      ] Record log in C:\Users\Administrator\.kivy\logs\kivy_16-03-20_59.txt

     from kivy.graphics.instructions import Callback, Canvas, CanvasBase, \
 ImportError: DLL load failed: The specified module could not be found.

The code is:

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


class TestApp(App):
    def build(self):
        return Button(text='Hello World')

TestApp().run()

Answer 1

Most probably you've installed kivy wrong or not completely. I think this problem appeared when people compiled kivy with the 1.8.0 portable package and it didn't compile graphic dlls.

Uninstall kivy from python and install it again through wheel (already compiled package), it's simple. Or try KivyInstaller .

我的解决方案是：pip install kivy.deps.glew
