\ xdef \ @ fontenc @ load @ list {\ @ fontenc @ load @ list在Rmarkdown中未定义的控制顺序 [英] \xdef\@fontenc@load@list{\@fontenc@load@list undefined control sequence in Rmarkdown

问题描述

我试图编写一个非常简单的Rmarkdown文件以pdf格式呈现，但是未定义的控制序列出现错误.

I've tried to write a very simple Rmarkdown file to render as pdf, but got an error for an undefined control sequence.

文件:

---
title: "Untitled"
author: "author"
date: "3/2/2020"
output: pdf_document
---

# whatever
fskjflsjflkj

保存为 test.Rmd 并编织(使用按钮)在 R 降价控制台中产生以下输出:

saved as test.Rmd and knit (with the button) produces the following output in the R markdown console:

processing file: test.Rmd
output file: test.knit.md

! Undefined control sequence.
l.115 \xdef\@fontenc@load@list{\@fontenc@load@list

Error: LaTeX failed to compile test.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See test.log for more info.
Execution halted

以下是相关的 test.log 部分:

如果我尝试使用 pdflatex ， lualatex 或 xelatex 进行编译都无所谓，则错误是相同的.

It doesn't matter if I try to compile it with pdflatex, lualatex or xelatex the error is the same.

我正在Ubuntu 18.04机器上进行所有更新和升级(以root身份获取更新& apt并获得升级)，并在运行 tlmgr update之后-自我-全部.

I'm working on an Ubuntu 18.04 machine with everything updated and upgraded (apt-get update && apt-get upgrade as root) and after running tlmgr update --self --all.

如何让Rmarkdown重新编织为pdf?

How can I get Rmarkdown to knit to pdf again?

推荐答案

尝试使用

fmtutil-sys --all

使用那些新的源(用tlmgr更新)重建格式文件.

to rebuilt the format files using those new sources (updated with tlmgr).
