我正在使用 Rmarkdown（以及 Pandoc）在 Ubuntu 18.04 上创建 PDF。但是，我收到以下错误

答案1
我不知道我做错了什么。我最终使用这个答案，并删除以下目录和texmaker
sudo rm -rf /usr/share/texmf/
rm -rf ~/texmf/
sudo apt-get remove texmaker
sudo apt autoremove
然后我重新安装了大部分软件包，如下所示
sudo apt-get install texlive-fonts-recommended
sudo apt-get install texlive-fonts-extra
sudo apt-get install texlive-latex-extra
sudo apt-get install texmaker
然后一切就正常了。
