我在编译一个简单的 Rmarkdown 文件时遇到问题，我对解决方案一无所知。这是问题所在：
我要编译的文件
这是一个没有 R 代码的简单文档，只有文本。在标题中：标题、作者、日期和output: pdf_document.
软件包是如何安装的
我安装了软件包rmarkdown并tinytex使用install.packages("tidyverse"). TinyTex（发行版）是这样安装的：tinytex::install_tinytex().
错误
> rmarkdown::render("~/document.Rmd", "pdf_document")
processing file: document.Rmd

#1 尝试：重新安装tinytex
我尝试卸载 ( tinytex::uninstall_tinytex())，再次安装 ( tinytex::install_tinytex()) 并重新安装 ( tinytex::reinstall_tinytex())，但错误仍然存在。
#2 尝试：安装lmodern
虽然tinytex::check_installed("lm") == TRUE，我尝试lmoden使用tinytex::tlmgr_install("lmodern").
安装

一些观察
- 我在全新安装 Arch Linux 时遇到了这个问题（已安装 wget）
- 我总是以这种方式安装
rmarkdown，tinytex即使在 Arch 上也是如此，而且每次都运行良好。 - 我在 Windows 机器和 Ubuntu 机器上进行了尝试，它按预期工作。
- RStudio 上的 knit 按钮也不起作用
