直到最近，我才能够从 Rmd 文件创建 pdf。
遇到麻烦我已按照建议更新 tinytex 并更新所有软件包（我曾经有 Miktex，后来改为 tinytex）
以这个基本示例为例：
---
title: "This is a report"
output:
pdf_document:
keep_tex: yes
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE, warning = FALSE, message = FALSE)
options(tinytex.verbose = TRUE)
```
This is a report
我收到以下错误：
"C:/Program Files/RStudio/bin/pandoc/pandoc" +RTS -K512m -RTS reports.utf8.md --to latex --from markdown+autolink_bare_uris+tex_math_single_backslash --output reports.tex --lua-filter "D:\Mes Donnees\R\win-library\4.0\rmarkdown\rmarkdown\lua\pagebreak.lua" --lua-filter "D:\Mes Donnees\R\win-library\4.0\rmarkdown\rmarkdown\lua\latex-div.lua" --self-contained --highlight-style tango --pdf-engine pdflatex --variable graphics --variable "geometry:margin=1in"

显然，没有丢失的包裹，所以我不知道发生了什么？
（对于信息，创建word文件或html文件没有问题；并且文件reports.pdf在项目目录中尚不存在，也没有被其他应用程序打开）。
reports.log 提供以下内容。

生成的tex文件没有问题，我使用了另一种策略并将pdf的创建分解为两个步骤：
xelatex --no-pdf ess.tex
xdv 文件的创建没有任何问题。然后我尝试使用将文件转换为pdf
xdvipdfmx -vv ess.xdv
然后出现问题：

ess.xdv -> ess.pdf
xdvipdfmx:fatal: Unable to open "ess.pdf".
No output PDF file written.
pdf文件似乎被锁定在某个地方。但是，我没有要求预览 pdf 文件，也没有任何 ess.pdf 预先存在于目录中！
加起来 出于绝望，我在一个没有空格的名称（D:/Ess）而不是一个有空格的目录（D:/Mes Donnees/Ess/）的新项目目录中再次尝试，这次成功了。
在早期版本中，我从未遇到过目录名称的任何问题。Rmarkdown 或 tinytex 中是否有任何变化导致了这个新问题？
