I have tried many ways to include a module installed by luarocks in a tex file to be processed by lualatex, but all methods give me

/texmf-dist/tex/luatex/lualibs/lualibs-basic-merged.lua:381: attempt to call 
a nil value (field 'cpath specification')
stack traceback:
        ...0/texmf-dist/tex/luatex/lualibs/lualibs-basic-merged.lua:381: in field '?'
        ...0/texmf-dist/tex/luatex/lualibs/lualibs-basic-merged.lua:403: in function <
...0/texmf-dist/tex/luatex/lualibs/lualibs-basic-merged.lua:395>
        [C]: in function 'require'
        [\directlua]:1: in main chunk.

I've tried Using LuaLaTeX and SQLite3 and the package luapackageloader. I have also played with setting package.path and package.cpath. The goal for me is to load the path module from penlight. And for that, I've tried both

\directlua{
  require("pl")
  path = require("pl.path")
}

and

\directlua{
  path = require("path")
}

Everything gave the same error quoted below. What did I do wrong?

Thanks!

PS. I'm running everything on a clean Ubuntu Bionic installation.

  • Maybe you could change the title to "Requiring a dynamic library gives error in lualatex from TeXLive 2020" or similar, because this is what people will look for in the next weeks/months.

  • Not sure if it's the same problem or not, but I run into similar issue with axessibility package. Fixed by putting file axessibility.lua into one of the folders returned by kpsewhich -show-path=lua, then running texhash (which was a crucial step I forgot to make). Sep 8, 2020 at 21:17

You will need to compile your document with --shell-escape starting with LuaTeX 1.12, which is shipped with TexLive 2020 (see https://tug.org/pipermail/luatex/2020-March/007333.html).

  • @reportaman: Are you sure? Requiring a binary module should require --shell-escape otherwise the argument is quite pointless.
