R version 4.1.0 (2021-05-18) -- "Camp Pontanezen" Copyright (C) 2021 The R Foundation for Statistical Computing Platform: x86_64-w64-mingw32/x64 (64-bit) 报错如下： ! Package inputenc Error: Unicode character 缁?(U+7EC3) (inputenc) not set up for use with LaTeX. Try other LaTeX engines instead (e.g., xelatex) if you are using pdflatex. See https://bookdown.org/yihui/rmarkdown-cookbook/latex-unicode.html 错误: LaTeX failed to compile Rmarkdown练习1.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips.

yanglin9909 请提供一份能展现这个问题的 R Markdown 文档，内容越少越好。

CyrusYip --- title: "Rmarkdown 练习1" output: pdf_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) ``` ## R Markdown This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>. When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this: ```{r cars} summary(cars) ``` ## Including Plots You can also embed plots, for example: ```{r pressure, echo=FALSE} plot(pressure) ``` Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot. 基本上没改动，升级 R 4.1.0 之后就出现了，R 4.0.5 没有问题 😅

请把文档放到三个反引号里面，比如这样： ``` 一个文档 ``` 发帖前请学习新手须知的 Markdown 语法。

Knit R Markdown file to PDF 报错

CyrusYip 我重新试了一下，把文档里的中文改为英文，可以正常导出pdf，目前是R markdown里有中文报错，有没有解决办法啊？谢谢 😀

CyrusYip

yanglin9909 可以用 rticles 包的 CTeX 模板。

CyrusYip 谢谢 😀

yanglin9909 系统环境相关信息可以通过运行xfun::session_info()生成。看了下你的 latex 引擎是 pdflatex，你试着显式的将其定义为 xelatex，如：

title: "Rmarkdown练习1"
documentclass: ctexart
output: 
  rticles::ctex:
    latex_engine: xelatex

另外，你最好在 RStudio 里设置下编译 PDF 默认的引擎为 XeLaTeX，具体步骤：Tools -> Global Options -> Sweave -> Typeset LaTex into PDF using

如果问题仍然没有得到解决，那么你最好把 Rmarkdown-练习4.log 和 Rmarkdown-练习4.tex 里的内容也一并贴上来，让其他人帮忙看看，LaTeX 这块我懂的也非常有限。

到处pdf还是报错，html和word都没有问题，谢谢答复 😀

yanglin9909 我很纳闷，为什么还是 pdflatex 引擎。YAML里的latex_engine: xelatex被计算机无视了吗？{rticles} 包的信息也没有。麻烦你再试试下面这个

title: "Rmarkdown练习1"
documentclass: ctexart
output: 
  rticles::ctex:
    latex_engine: xelatex
CJKmainfont: Microsoft YaHei

还有更多信息可以提供吗？比如 Rmarkdown-练习4.tex 和 Rmarkdown-练习4.log
