Windows环境下安装R包tinytex因xfun版本不兼容失败求助

在Windows环境下安装R包tinytex时遇到问题，推测是依赖包xfun的版本兼容问题，报错信息如下：

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  namespace 'xfun' 0.43 is being loaded, but >= 0.48 is required
Calls: <Anonymous> ... namespaceImportFrom -> asNamespace -> loadNamespace

初始渲染错误 #

最初需求是用pagedown将Markdown文件转为PDF，渲染失败提示安装tinytex，错误信息如下：

Error: LaTeX failed to compile test.tex. See [debugging tips URL] for debugging tips.
In addition: Warning messages:
1: In system2(..., stdout = if (use_file_stdout()) f1 else FALSE, stderr = f2) :
  "\"pdflatex\"" not found
2: In system2(...) : "\"pdflatex\"" not found
Execution halted

No LaTeX installation detected (LaTeX is required to create PDF output). You should install a LaTeX distribution for your platform: [LaTeX download URL]

  If you are not sure, you may install TinyTeX in R: tinytex::install_tinytex()

  Otherwise consider MiKTeX on Windows - [MiKTeX download URL]

  MacTeX on macOS - [MacTeX download URL]
  (NOTE: Download with Safari rather than Chrome _strongly_ recommended)

  Linux: Use system package manager

提问 #

无法从CRAN安装xfun 0.49版本，请问如何成功安装tinytex（尽量避免使用Rtools）？
