My lua require statement fails to search the correct path. How can I modify the installation or my environment so that Lua require statements work?

under MAC OS Sonoma 14.2.1

luaclient.lua script line 2 is:

local socket = require('socket')

When the script is run, it yields:

lua: luaclient.lua:2: module 'socket' not found:
    no field package.preload['socket']
    no file '/usr/local/share/lua/5.4/socket.lua'
    no file '/usr/local/share/lua/5.4/socket/init.lua'
    no file '/usr/local/lib/lua/5.4/socket.lua'
    no file '/usr/local/lib/lua/5.4/socket/init.lua'
    no file './socket.lua'
    no file './socket/init.lua'
    no file '/usr/local/lib/lua/5.4/socket.so'
    no file '/usr/local/lib/lua/5.4/loadall.so'
    no file './socket.so'
stack traceback:
    [C]: in function 'require'
    luaclient.lua:2: in main chunk
    [C]: in ?

socket is installed here:

/Users/user_name/.luarocks/share/lua/5.4

Lua interpreter says:

Lua 5.4.7 Copyright (C) 1994-2024 Lua.org, PUC-Rio

print(package.path) 

/usr/local/share/lua/5.4/?.lua;/usr/local/share/lua/5.4/?/init.lua;/usr/local/lib/lua/5.4/?.lua;/usr/local/lib/lua/5.4/?/init.lua;./?.lua;./?/init.lua

Trying:

set LUA_PATH '/Users/perryhorwich/.luarocks/share/lua/5.4/?.lua'

... in the shell, gives the same error as though LUA_PATH has no effect on the lookup for 'socket'

What am I missing?

Solution

  • Adding this to my code:

    package.cpath ="/Users/user_name/.luarocks/lib/lua/5.4/?.so;" .. package.cpath
package.path = "/Users/user_name/.luarocks/share/lua/5.4/?.lua;" .. package.path

    ... worked.
