是否有人使用过kartograph.js和'kartograph.py'库？
你知道我是否需要'kartograph.py'才能运行吗？如何在不安装python的情况下使用'kartograph.py'库？因为在“ kartograph.js”中构建“ BBOX”时遇到“ kartograph.js”问题

kartograph.js中的错误：

....
if (height === 0) height = width * .5;
        alert(width);
        me.viewport = new kartograph.BBox(0, 0, width, height);
**Uncaught TypeError: undefined is not a function**
        me.paper = me.createSVGLayer();
        me.markers = [];
        me.pathById = {};
        me.container.addClass('kartograph');
    }
....

谢谢您的帮助

最佳答案

您需要生成要与kartograph.py一起使用的地图，因此这可以直接回答您的下一个问题，是的，您需要安装Python才能使用它。没有Python解释器，您将无法运行用Python编写的内容。

我不太确定您从哪里读到了有关BBox方法的信息，但是文档说的却有些不同：http://kartograph.org/docs/kartograph.js/
