Hi Ruby,
Welcome to the LuaRT Community.
Under Windows, using a standalone Lua interpreter (without its dependency on Lua54.dll) does not allow the use of Lua
binary modules (the binary module will not be loaded since it will desperately look for Lua54.dll).
See this answer from Mike Pall, author of LuaJIT, on the same topic:

As LuaRT matures, however, binary Lua modules become less necessary and a dependency-free LuaRT interpreter may be useful. LuaRT 0.9.4 will be released shortly, but LuaRT 0.9.5 may feature a LuaRT interpreter that does not require Lua54.dll (for both desktop and console applications).
Regards,
Samir
