Well, the point of `luarocks path` _is_ to ensure that the LuaRocks-installed modules are found. I see no other way of doing that. Is your bin/specl script resetting the package.path? I would expect something like this to work to your liking: $ luarocks path export LUA_PATH="/paths/set/by/luarocks/..." $ eval `luarocks path` $ echo $LUA_PATH /paths/set/by/luarocks/... $ LUA_PATH="./lib/?.lua;$LUA_PATH" lua -e 'print(package.path)' ./lib/?.lua;/paths/set/by/luarocks/... $ LUA_PATH="./lib/?.lua;$LUA_PATH" bin/specl # works as intended?...
