【问题描述】：

我正在使用docxtemplater 库来生成一个word 文件。当我在同一行中使用多个标签时，它会提示以下错误：

"error":{"name":"TemplateError","message":"Multi error","stack":"Error: Multi error\n    at new XTTemplateError (E:\\Users\\cstsang\\workspace\\coss_sla\\node_modules\\docxtemplater\\js\\errors.js:24:16)\n

下图为word文件模板情况，供大家参考。

当我删除所有{abc} 标签时，它工作正常。

publicAPI.js的代码片段如下：

let content = fs.readFileSync(path.resolve(__dirname, 'template.docx'), 'binary');
let zip = new PizZip(content);
let doc = new Docxtemplater(zip, { paragraphLoop: true, linebreaks: true });

声明let doc = new Docxtemplater(zip, { paragraphLoop: true, linebreaks: true });是publicAPI.js的第29行

标签： node.js ms-word docxtemplater

【解决方案1】：

在web page中搜索关键字“不平衡循环标签”后，找到了解决方案，模板应该如下：
