Kivy中打开.png文件的问题

Question

我在尝试使用kivy.garden.mapview，显然这个功能还在开发中，但我在想问题可能出在kivy/core/image/img_pygame.py这个文件上。

请问kivy和pygame支持.png格式的图片吗？

补充：

我用了自己的Python版本，最后终于搞定了。

看起来问题出在mscv编译器在找vcvarsamd64.bat这个文件，但这个文件不存在。

我用了以下解决方案：在构建/安装Python 2.7的C模块时出现错误

然后我把所有的glew头文件和库文件复制到了合适的包含文件夹里，最后我成功用pip install kivy安装了kivy。
