I find what I changed, when it loaded, it shows an error about maxminddb,
maxminddb.lua:151: dlopen(libmaxminddb.so, 5): image not found
So I changed from
local maxm = ffi.load('libmaxminddb.so') to
local maxm = ffi.load('libmaxminddb.dylib')
Maybe that's the reason.

I use Mac, do you know why it shows the error:
maxminddb.lua:151: dlopen(libmaxminddb.so, 5): image not found

u need https://github.com/maxmind/libmaxminddb#on-os-x-via-homebrew

	local _,status,resultTap = _dump_entry_data_list(entry_data_list)

	if status ~= MMDB_SUCCESS then
	return nil,'no data'
	end

	return json_decode(table.concat(resultTab)),nil
