未捕获的TypeError：无法读取CKEditor中未定义的属性'setSize'

Question

在Chrome中启动CKEditor时，出现下一个错误：

Uncaught Type Error cannot read property 'setSize'  of undefined ckeditor.js:323

这是脚本行：

 f.setSize("width",a,true);g&&(g.style.width="1%");j.setStyle("height",Math.max(b-(d?0:(f.$.offsetHeight||0)-(j.$.clientHeight||0)),0)+"px");g&&(g.style.width=
    "100%");this.fire("resize")};CKEDITOR.editor.prototype.getResizable=function(a){return a?this.ui.space("contents"):this.container};CKEDITOR.domReady(function(){CKEDITOR.replaceClass&&CKEDITOR.replaceAll(CKEDITOR.replaceClass)})})();CKEDITOR.config.startupMode="wysiwyg";

有人可以帮我解决这个错误吗？ 谢谢
