问题描述
我正在尝试将R markdown文件编织为html / pdf文档。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R，Rstudio和tinytex软件包的最新版本，但是我不在网络驱动器上工作（即Rmd文件位于C：/）。
我重新安装了tinytex，这导致了一些错误消息：
tinytex::reinstall_tinytex()
If reinstallation fails,try install_tinytex() again. Then install the following packages:

根据here中的建议，我试图验证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，似乎还没有将tinytex路径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（请参见例如here）。 / p>
tinytex::tinytex_root()
[1] "C:\\Users\\ann\\AppData\\Roaming\\TinyTeX"
Sys.getenv('PATH')

编辑：再次安装tinytex也无济于事，我从编织中得到了相同的错误消息。这是安装后打印的内容：
tinytex::install_tinytex()

安装MiKTeX之后，编织文档时不再看到Latex问题，但是与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
我该如何解决这些问题以编制Rmarkdown文档？感谢您的帮助！
解决方法
也可以尝试安装Miketex，就像Edo所说的那样，像Rmarkdown建议的那样安装tinytex。
很明显，您的问题是未安装乳胶，所以只需尝试重新安装并安装另一个乳胶程序，您就可以编织好！
