如何将mxgraph集成到webpack中？

Question

我正在尝试将mxgraph库集成到webpack / rails项目中。

但是我面临一个问题。

我尝试遵循仓库中的webpack示例： https://github.com/jgraph/mxgraph/blob/master/javascript/examples/webpack/src/anchors.js

但是，当我加载包含容器的页面时，它会引发错误：

Uncaught TypeError: Cannot read property 'prototype' of undefined

对于此对应的行：

mxGraph.prototype.getAllConnectionConstraints = function(terminal, source)

我认为此声明无法正常工作：

var mxgraph = require("../../../node_modules/mxgraph/javascript/dist/build"),
    mxGraph = mxgraph.mxGraph,
    mxShape = mxgraph.mxShape,
    mxConnectionConstraint = mxgraph.mxConnectionConstraint,
    mxPoint = mxgraph.mxPoint,
    mxPolyline = mxgraph.mxPolyline,
    mxEvent = mxgraph.mxEvent,
    mxRubberband = mxgraph.mxRubberband,
    mxCellState = mxgraph.mxCellState;

总之，将mxgraph包含到webpack / rails项目中的正确方法是什么？

提前谢谢！
