LaTeX错误：包装颜色的选项冲突

如何解决LaTeX错误：包装颜色的选项冲突

只需将R更新到版本4.0.2（从3.6.3开始），将rmarkdown更新到v2.3（从1.13开始）。但是我在编织到pdf时遇到了几个问题。我在新rmarkdown（pdf）的yaml部分中使用了以下代码，其余内容保持不变，但出现标题错误。

---
title: "Untitled"
output: 
  pdf_document:
    fig_height: 6
    fig_width: 9
    includes:
      in_header: greek.tex
    latex_engine: xelatex
    pandoc_args: [
                   "--variable","geometry:paperwidth=8.27in","--variable","geometry:paperheight=11.69in","geometry:left=0.75in","geometry:right=0.75in","geometry:top=0.75in","geometry:bottom=0.75in"
                 ]

---

greek.tex内容：

\usepackage{fontspec}
\usepackage{hyperref}
\usepackage{longtable}
\usepackage{rotating}
\usepackage{tabularx}
\usepackage{pdflscape}
\usepackage{float}
\usepackage[usenames,dvipsnames]{color}
\usepackage[normalem]{ulem}
\usepackage[bottom]{footmisc} 
\setmainfont[Scale=1.0]{Segoe UI} 
\setsansfont{Calibri}
\usepackage[font=small]{caption}
\captionsetup[table]{name=Πίνακας}
\renewcommand{\baselinestretch}{1.2}

我还注意到编织到html时需要这样的HTML代码

<div class="text-center"> 

现在会产生错误，例如

! LaTeX Error: Environment text-center undefined.
