【问题描述】：
我正在尝试将 R markdown 文件编入 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，但出现了一些错误消息：
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here 中的建议，我尝试验证 R 是否可以找到编织所需的程序。它似乎找不到它们。
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 here）。
tinytex::tinytex_root()
[1] "C:\\Users\\ann\\AppData\\Roaming\\TinyTeX"
Sys.getenv('PATH')
[1] "C:\\Program Files\\R\\R-4.0.3\\bin\\x64;C:\\Program Files\\ImageMagick-7.0.8-Q16;C:\\Program Files (x86)\\Intel\\iCLS Client\\;C:\\Program Files\\Intel\\iCLS Client\\;C:\\WINDOWS\\system32;C:\\WINDOWS;C:\\WINDOWS\\System32\\Wbem;C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\;C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\DAL;C:\\Program Files\\Intel\\Intel(R) Management Engine Components\\DAL;C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\IPT;C:\\Program Files\\Intel\\Intel(R) Management Engine Components\\IPT;C:\\Program Files\\Microsoft VS Code\\bin;C:\\Program Files (x86)\\Windows Kits\\8.1\\Windows Performance Toolkit\\;C:\\Users\\hriihima\\AppData\\Local\\Continuum\\anaconda3;C:\\WINDOWS\\System32\\OpenSSH\\;C:\\Program Files (x86)\\NVIDIA Corporation\\PhysX\\Common;C:\\Program Files\\Git\\cmd;C:\\HYAPP\\rtools3.5\\bin;C:\\HYAPP\\rtools3.5\\gcc-4.6.3\\bin;C:\\HYAPP\\rtools3.5\\mingw_32\\bin;C:\\HYAPP\\rtools3.5\\mingw_64\\bin;C:\\Program Files\\PuTTY\\;C:\\Program Files\\Common Files\\ThinPrint\\;C:\\Users\\ann\\AppData\\Local\\Microsoft\\WindowsApps;"

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

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信息：
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？感谢您的帮助！
【问题讨论】：

如错误提示，尝试以这种方式再次安装：
tinytex::install_tinytex() -
在这种情况下混合了两个问题。一是LaTeX最初没有安装，你修复了它（
tinytex::tinytex_root()的输出显示你正确安装了TinyTeX，它不必在PATH变量中）。另一个是您似乎在网络驱动器上。这是 rmarkdown 中的一个已知问题：github.com/rstudio/rmarkdown/issues/1268 该线程中的此评论可能会有所帮助：github.com/rstudio/rmarkdown/issues/1268#issuecomment-651784184 我们将在不久的将来进一步调查此问题。谢谢！ -
谢谢大家。我尝试了 Edo 和 Daniel 的建议，但没有帮助。关于 Yihui 的评论 - 我的 R markdown 评论位于 C:/Documents/ 文件夹中，所以我不认为我在网络驱动器上。还是我理解错了？
-
对不起 - 我认为 Documents 文件夹毕竟在网络驱动器上，所以我现在就试试 Yihui 的建议。
-
是的，问题与网络驱动器有关。现在问题已经解决了。谢谢大家！
