lua脚本出现模块未找到的错误

我正在运行一个lua脚本。

#!/usr/bin/lua

require("posix")
require("math")
require("os")
-- ...

它出现以下错误:

xctest7b # lua attack.lua
lua: attack.lua:3: module 'posix' not found:
        no field package.preload['posix']
        no file './posix.lua'
        no file '/usr/share/lua/5.1/posix.lua'
        no file '/usr/share/lua/5.1/posix/init.lua'
        no file '/usr/lib64/lua/5.1/posix.lua'
        no file '/usr/lib64/lua/5.1/posix/init.lua'
        no file './posix.so'
        no file '/usr/lib64/lua/5.1/posix.so'
        no file '/usr/lib64/lua/5.1/loadall.so'
stack traceback:
        [C]: in function 'require'
        attack.lua:3: in main chunk
        [C]: ?

我已经安装了luarocks和luaposix两者。luaposix的安装完成情况如下:

luaposix 33.3.1-1 现已在 /usr/local 中构建和安装

有关我真正需要安装的内容是否有任何提示？

路径:

xctest7b # lua -e "print(package.cpath)"
/usr/local/lib/lua/5.3/?.so;/usr/local/lib/lua/5.3/loadall.so;./?.so

xctest7b # lua -e "print(package.path)"
/usr/local/share/lua/5.3/posix;/usr/local/share/lua/5.3/?.lua;/usr/local/share/lua/5.3/?/init.lua;/usr/local/lib/lua/5.3/?.lua;/usr/local/lib/lua/5.3/?/init.lua;./?.lua;./?/init.lua;

xctest7b # find /usr/local -name posix
/usr/local/share/lua/5.3/posix
