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
