如何在Kivy中正确导入MapSource？

Question

我正在克隆一个使用Kivy快速原型作为接口的存储库。它最后一次更新是在一年前，最初的开发人员没有回应问题-我想我应该在这里问一下。

该程序使用MapSource库，并按如下方式导入它：

#:import MapSource mapview.MapSource

我得到了错误：

Unable to import package 'mapview.MapSource'

这是我第一次和Kivy一起工作。导入MapSource的语法是什么

以下是错误的完整输出：

感谢大家的帮助。谢谢!

你当然想要garden.mapview

要安装它，你可以使用garden这个kivy工具来安装kivy模块，如果已经安装了garden (在安装kivy时应该是这样的)，它应该像下面这样简单。

garden install --app mapview

(--app不是强制性的，它只是将花放在应用目录中，而不是放在~/.kivy/garden中)

如果没有，你可以pip install kivy-garden或者你可以在你的应用程序中创建一个lib目录并git clone git@github.com:kivy-garden/garden.mapview.git到其中，因为这就是该工具所做的事情。
