Describe the bug Upon running lua ./cli.lua --preset Strong ./test.lua i get the following output

lua: ./src/obfuscator/util.lua:7: module 'bit' not found:
    no field package.preload['bit']
    no file './src/bit.lua'

Expected behavior The file was supposed to run properly

To Reproduce Steps to reproduce the behavior: Have an arch system with the following lua-related packages installed: lua 5.4.3-1 lua51 5.1.5-9 lua52 5.2.4-5 lua53 5.3.6-1 luajit 2.0.5-3 luarocks 3.8.0-1

git clone the repo, cd into it, and do lua ./cli.lua --preset Strong ./test.lua

Solution:

• Install liblua5.2 deps and lua5.2.
• Install LuaRocks for lua5.2
  • instead of ./configure, use ./configure --lua-version=5.2

    wget https://luarocks.org/releases/luarocks-3.8.0.tar.gz
    tar zxpf luarocks-3.8.0.tar.gz
    cd luarocks-3.8.0
    ./configure --lua-version=5.2 && make && sudo make install
    sudo luarocks install luasocket
    lua

    > require "socket"

  • make sure to install any required deps if run into issues
• Install the dependency lua-bit-numberlua
  • not sure if package is available anymore through luarocks. install manually.

    DOWNLOAD/INSTALLATION
    If using LuaRocks:
    luarocks install lua-bit-numberlua
    Otherwise, download <https://github.com/davidm/lua-bit-numberlua/zipball/master>.
    Alternately, if using git:
    git clone git://github.com/davidm/lua-bit-numberlua.git
    cd lua-bit-numberlua
    Optionally unpack:
    ./util.mk
    or unpack and install in LuaRocks:
    ./util.mk install 

• Clone this repo and have fun.
  • may have to change require 'bit' to require 'bit.numberlua'

Fixed

The issue was, that a package was required, that is not present on every system. This was due to me only testing using luajit, where the "bit" package is included. I changed

local bit32 = require("bit");

to

local bit32 = require("prometheus.bit").bit32;

This change is incorporated in the newest release v0.1.6.

Please keep in mind that prometheus was developed for lua51, so it may fail when running on other lua versions.

Thanks to @tornadia for proposing a quick fix for this issue.
