Question

尝试使用kivy.garden.mapview，显然这仍然是一项正在进行的工作，但想知道问题是否可能在kivy / core / image / img_pygame.py

kivy / pygame支持.png图片吗？

-B

编辑：

使用我自己的Python发行版，最终让它发挥作用。

似乎问题是mscv编译器正在寻找vcvarsamd64.bat，但它不存在。

使用以下解决方案：Errors while building/installing C module for Python 2.7

然后我将所有glew标题和libs复制到相应的包含文件中，我终于使用pip install kivy正确安装了kivy

Answer 1

应该支持png，我不确定问题是什么。可能是pygame提供者不能做png而你缺少一个更好的提供者，但这似乎不太可能。

您是否可以运行mapview附带的示例？例如其github repo的examples目录中的simple_map.py。

Answer 2

结果我试图将 vector mbtiles加载到Mapview中，但它不支持。它确实支持 raster mbtiles，例如https://docs.djangoproject.com/en/1.8/ref/models/querysets/#django.db.models.query.QuerySet.first

在Kivy中发布打开的.png文件
