Question

我正在尝试在RStudio中编织RMD文件，但出现以下错误

yaml :: yaml.load（string，...）中的错误：扫描仪错误：在第31行的第5列扫描普通标量时，发现了制表符在第34行第1栏违反了意图的调用：... parse_yaml_front_matter-> yaml_load_utf8->执行停止

rmd文件的标题如下：

> --- 
> title: "Homework 4" 
> author: NAME OF THE AUTHOR, Fall 2018 
> date: Due Friday, September 30, 11:59pm 
> subparagraph: yes

任何想法是什么原因造成的？错误指向第31行中的字符“ n”，我不确定该如何解决。任何帮助或建议都将受到高度赞赏。

我已经在Mac和PC上都安装了RStudio的情况下进行了尝试。

假设行首的>是复制和粘贴后的剩余内容（肯定不会出现在文件中），则您有一个YAML文档，其开头如下：

--- 
title: "Homework 4" 
author: NAME OF THE AUTHOR, Fall 2018 
date: Due Friday, September 30, 11:59pm 
subparagraph: yes 
output:  
pdf_document:
    number_sections: true header-includes:
  - \setcounter{secnumdepth}{1}

，这是无效的，因为您不能同时拥有键pdf_document的映射值和序列（也要减少缩进）。结合行内冒号和行尾冒号的组合，可能会使解析器混乱

您可能希望将其更改为以下内容：

--- 
title: "Homework 4" 
author: NAME OF THE AUTHOR, Fall 2018 
date: Due Friday, September 30, 11:59pm 
subparagraph: yes 
output:  
pdf_document:
    number_sections: true
header-includes:
  - \setcounter{secnumdepth}{1}
