使用代码
var book = ePub("https://standardebooks.org/ebooks/marcus-aurelius/meditations/george-long/dist/marcus-aurelius_meditations.epub");
var rendition = book.renderTo("area", {width: 600, height: 400});
在调用book.renderTo（）时引发错误，并显示以下错误消息：
epub.min.js:formatted:10024 Uncaught Error: Not an Element at e.value (epub.min.js:formatted:10024) at e.value (epub.min.js:formatted:10030) at e.value (epub.min.js:formatted:2946) at e.<anonymous> (epub.min.js:formatted:4500) at e.value (epub.min.js:formatted:1925) at epub.min.js:formatted:1954
有人知道错误的根源吗？
