how to install lua liberec on mac os?

I do not know how to do this

main.lua

local luajson = require "lunajson"

local file = io.open("main.json", "r")
local data = file:read("*all")
file:close()

local tbl = luajson.decode(data)
print(tbl["name"])

main.json

{
    "name": "Timofey"
}

terminal:

lua: main.lua:1: module 'lunajson' not found:
	no field package.preload['lunajson']
	no file '/usr/local/share/lua/5.4/lunajson.lua'
	no file '/usr/local/share/lua/5.4/lunajson/init.lua'

I tried restarting the mac, but it still gives an error
