Question

我一直在制作一些Kivy应用程序并且它们可以在Python34中正常工作但由于某些原因突然停止使用Python27，之后在代码中没有任何变化。我一直在寻找一个解决方案，并尝试添加东西到路径，卸载和重新安装gstreamer，更新Python，更新kivy，更新依赖等等，没有解决它！这是我在控制台上获得的输出：

[WARNING           ] [Image       ] Unable to load image <C:\Python27\lib\site-packages\kivy\data\glsl\default.png>

[CRITICAL          ] [Window      ] Unable to find any valuable Window provider at all!

最近，主分支中的依赖关系发生了变化。由于路径上的DLL冲突，很可能会引发异常。

我遇到了zlib1.dll文件与Intel驱动程序的冲突。然而，在Kivy中有一个针对依赖性的修复来防止这种冲突。如果没有PATH share/sdl2/bin中的同名文件，请将相关性更新为最新版本，或检查share/glew/bin中的文件夹。

如果有，请确保在崩溃窗口创建的路径之前放置的Kivy依赖路径。

尝试使用Python27运行Kivy应用程序时出错：引发异常（'SDL2：无法加载图像'）
