我使用的是 Manjaro Linux。我已经texlive-most安装了。
我正在尝试使用 pandoc 从 md 制作 pdf 文件。但是，我不断收到Permission denied错误。我尝试过使用pdflatex和pdfroff。
使用默认值运行--pdf-engine=pdflatex：
$ pandoc test.md -o test.pdf

Error producing PDF.
This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Arch Linux) (preloaded format=pdflatex)
I can't find the format file `pdflatex.fmt'!
快速调查：
$ ll /usr/bin/mktexfmt
lrwxrwxrwx 1 root root 7 Nov 1 2019 /usr/bin/mktexfmt -> fmtutil
$ ll /usr/bin/fmtutil
lrwxrwxrwx 1 root root 48 Nov 1 2019 /usr/bin/fmtutil -> /usr/share/texmf-dist/scripts/texlive/fmtutil.pl
$ ll /usr/share/texmf-dist/scripts/texlive/fmtutil.pl
-rwxr-xr-x 1 root root 49K Nov 1 2019 /usr/share/texmf-dist/scripts/texlive/fmtutil.pl
$ locate pdflatex.fmt
/var/lib/texmf/web2c/pdftex/pdflatex.fmt
$ ll /var/lib/texmf/web2c/pdftex/pdflatex.fmt
-rw-r--r-- 1 root root 7.7M Jun 5 09:27 /var/lib/texmf/web2c/pdftex/pdflatex.fmt
运行--pdf-engine=pdfroff：
$ pandoc --pdf-engine=pdfroff test.md -o test.pdf
pandoc: pdfroff: createProcess: runInteractiveProcess: exec: permission denied (Permission denied)
pandoc可以运行sudo，但我不想用它sudo来生成 pdf。我看到这mktexfmt得到了execute许可，并且pdflatex.fmt得到了read每个人的许可。我还想使用默认引擎pdflatex而不是其他引擎。
我应该如何解决这个Permission denied问题？
答案1
我已经找出问题所在了。我sudo firecfg在安装 pandoc 后运行，这pandoc导致被 firejail 符号链接和沙箱化。通过sudo rm /usr/local/bin/pandoc删除 firejail 的 pandoc 符号链接，有效地将 pandoc 从沙箱中删除，问题得到了解决。
