我安装了 pdfkit，现在我正在尝试将文本添加到 pdf 并将其保存到磁盘。我正在关注来自http://blog.nodeknockout.com/post/9134350698/countdown-to-ko-8-introduction-to-pdfkit的教程，但我一直在下面收到错误消息。如何使用 node.js 和 pdfkit 添加文本？

谢谢你。源代码：

 doc = new PDFDocument();
doc.moveTo(300, 75)
   .lineTo(373, 301)
   .lineTo(181, 161)
   .lineTo(419, 161)
   .lineTo(227, 301)
   .fill('red', 'even-odd');

    var loremIpsum = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam in...';

    doc.y = 320;
    doc.fillColor('black')
   .text(loremIpsum, {
       paragraphGap: 10,
       indent: 20,
       align: 'justify',
       columns: 2
   });


    doc.write('out.pdf');

错误

应该是doc.text因为在.fillcall 和之间还有其他代码行，所以会.text产生语法错误。
