LuaJIT not seeing rocks installed by LuaRocks

Question

lua -e "print(package.path)"

./?.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua;/usr/lib/lua/5.1/?.lua;/usr/lib/lua/5.1/?/init.lua

luajit -e "print(package.path)"

./?.lua;/usr/local/share/luajit-2.0.0-beta8/?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua

I've tried appending lua's package.path, no dice though. LuaJIT just can't seem to find any of the rocks, it's weird. What should I do here?

Answer 1

If you've installed the module using luarocks, but not as root, stick: require 'luarocks.loader' before you include the module and it should be included without the error.

Answer 2

Two suggestions:

1. Install rocks as root to get them in /usr/local
2. Use ldconfig to update shared library cache

Example:

e@eSammy:~$ sudo luarocks install lsqlite3
[sudo] password for e:
Installing http://luarocks.org/repositories/rocks/lsqlite3-0.8-1.src.rock...
...
lsqlite3 0.8-1 is now built and installed in /usr/local/ (license: MIT/X11)
e@eSammy:~$ sudo /sbin/ldconfig
[sudo] password for e:
e@eSammy:~$ rlwrap luajit

Answer 3

On a Mac? Running brew?

Install lua51, which is packaged with luarocks aliased as luarocks-5.1:

brew install luajit lua51
eval `luarocks-5.1 path --bin` # exports LUA_PATH, LUA_CPATH, PATH
luarocks-5.1 install socket
luajit -e 'print(require("socket"))'
