I'm getting this error when trying to require LuaSocket with Lua5.3

error loading module 'socket.core' from file '/usr/local/lib/lua/5.3/socket/core.so': /usr/local/lib/lua/5.3/socket/core.so: undefined symbol: luaL_openlib

Console Output with demonstration:

How can I make luaL_openlib to work with Lua5.3?

  • it ran perfectly fine on my machine. Could maybe tell us how you installed socket, and lua? ā€“ Ace shinigami Dec 11 '17 at 16:04

I faced the same issue and solved with this link: https://luarocks.org/

My problem is that I was using lua 5.3 and my luarocks was downloading modules for lua 5.1
