尝试渲染页面时出现此错误

Uncaught (in promise) TypeError: this.getChildren is not a function
at html2canvas.js:2014
at prototype.js:298
at prototype.js:266
at Array._each (prototype.js:473)
at Array.each (prototype.js:264)

at new NodeParser (html2canvas.js:1860)
at renderWindow (html2canvas.js:1018)
at html2canvas.js:1005

这是我渲染页面的代码

 var runH2c = function(){
    try {
        /*option.testTop = scrollValueX;
        options.logging = true;
        options.onrendered = options.onrendered || function( canvas ) {


        };*/
         var body = document.getElementsByTagName("body")[0]; 
window.html2canvas(body, {
    logging: true,
    type: 'view',
    onrendered: function(canvas) {
            $this.h2cCanvas = canvas;
            $this.h2cDone = true;

    }
})
    /*    window.html2canvas([ document.body ], options);*/



    } catch( e ) {
        $this.h2cDone = true;
        log("Error in html2canvas: " + e.message);
    }
};

这是html2canvas上有错误的代码

NodeParser.prototype.getChildren = function(parentContainer) {

return flatten([].filter.call(parentContainer.node.childNodes, renderableNode).map(function(node) {
    var container = [node.nodeType === Node.TEXT_NODE ? new TextContainer(node, parentContainer) : new NodeContainer(node, parentContainer)].filter(nonIgnoredElement);
    return node.nodeType === Node.ELEMENT_NODE && container.length && node.tagName !== "TEXTAREA" ? (container[0].isElementVisible() ? container.concat(this.getChildren(container[0])) : []) : container;
}, this));

};

html2canvas的版本是 - html2canvas 0.5.0-beta4 原型是 - 原型JavaScript框架，版本1.5.0_rc0 *（c）2005 Sam Stephenson

拜托，我需要帮助我的项目。我该怎么办？

html2canvas对原型的可枚举的冲突。
