問題描述
我從 kivy 開始.這是我正在運行的示例代碼.
I am starting with kivy. here is the sample code I am running.
import kivy
from kivy.app import App
from kivy.uix.button import Label
kivy.require('1.9.0')
class HelloApp(App):
def build(self):
return Label(text='Hello World!')
if __name__ == "__main__":
HelloApp().run()
這是我得到的回溯:

我在 Windows 10 64 位上運行.我已經安裝了除了 gstreamer 之外的所有依賴項，目前我不需要.
I am running on windows 10 64bits. I have installed all the dependencies except gstreamer which I won't need at the moment.
我也不確定為什么會收到此錯誤:
I am also not sure why I am getting this error:
[WARNING ] [Image ] Unable to load image <C:Python34libsite-packageskivydataglsldefault.png>
文件存在，我以管理員身份運行代碼以避免訪問權限問題.
The file exists and I am running my code as admin to avoid access rights problems.
謝謝.
推薦答案
您必須安裝 Kivy 的依賴項.
You have to install the dependencies for Kivy.
按照此處
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
會做你需要的.
