Where are the modules installed using luarocks

Question

I am trying to require a module I downloaded using luarocks using

require "lualogging"

but lua (and I!) cannot find where this module was downloaded to. Here is what I did

I have used apt-get to install luarocks, and then I ran

sudo luarocks install lualogging

I then ran

luarocks list

and received the following output

Installed rocks:

lualogging
1.3.0-1 (installed) - /usr/local/lib/luarocks/rocks

luasocket
3.0rc1-1 (installed) - /usr/local/lib/luarocks/rocks

Natural this led me to believe that lualogging was located in /usr/local/lib/luarocks/rocks, but running this command

find /usr/local/lib/luarocks/rocks "lualogging.lua"

returned nothing. What am I doing wrong here? This may be related, but I cannot find what my LUA_PATH environment variable is so it may be that it was never set? I'd like to be able to run require "lualogging" from any file regardless of where it is located in the filesystem, and then log to my heart's content. But I can't even find where lualogging.lua exists...

Answer 1

Run luarocks show lualogging. It will list all modules and where they are.

Answer 2

It should be require "logging" not require "lualogging"
