我正在尝试将 R markdown 文件编织到 html/pdf 文档中。这是我收到的错误消息：
output file: test.knit.md
pandoc.exe: test.utf8.md: openBinaryFile: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 1
Execution halted
No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: https://www.latex-project.org/get/
If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()
Otherwise consider MiKTeX on Windows - http://miktex.org
MacTeX on macOS - https://tug.org/mactex/
(NOTE: Download with Safari rather than Chrome _strongly_ recommended)
Linux: Use system package manager
我正在使用最新版本的 R、Rstudio 和 tinytex 软件包，并且我不在网络驱动器上工作（即 Rmd 文件位于 C:/ 中）。
我重新安装了 tinytex 导致一些错误消息：
tinytex::reinstall_tinytex()
If reinstallation fails, try install_tinytex() again. Then install the following packages:
tinytex::tlmgr_install(c("'\\ad.helsinki.fi\home\a\ann\Documents'", "CMD.EXE was started with the above path as the current directory.", "UNC paths are not supported.

根据此处的建议，我尝试验证 R 是否可以找到编织所需的程序。似乎找不到它们。
Sys.which('pdflatex')
pdflatex
""
此外，似乎 tinytex 路径未添加到系统环境变量 PATH 中，因为在 Sys.getenv('PATH') 中找不到 tinytex_root() 路径（参见例如此处）。
tinytex::tinytex_root()
[1] "C:\\Users\\ann\\AppData\\Roaming\\TinyTeX"
Sys.getenv('PATH')

已编辑：再次安装tinytex也无济于事，我从编织中收到相同的错误消息。这是安装后打印的内容：

安装 MiKTeX 后，我在编织文档时不再看到 Latex 问题，但与 openBinaryFile 相关的第一个错误仍然存在。这是我的示例 Rmd 脚本：
---
title: "test"
output:
html_document: default
---
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
testing
```{r}
print("hi")
### 1. Testing
```
这是它打印出来的错误消息：
output file: test.knit.md
pandoc.exe: test.utf8.md: openBinaryFile: does not exist (No such file or directory)
Error: pandoc document conversion failed with error 1
Execution halted
如何解决这些问题才能编写我的 Rmarkdown 文档？感谢帮助！
