luarocks install lua-resty-aws failed on Mac OS

[AllenFang]

hello guys, I'm trying to install this package in my Mac OS(M2) but encountered an issue:

luaexpat 1.5.1-1 depends on lua >= 5.1 (5.4-1 provided by VM)
env MACOSX_DEPLOYMENT_TARGET=11.0 gcc -O2 -fPIC -I/opt/homebrew/opt/lua/include/lua5.4 -c src/lxplib.c -o src/lxplib.o -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include -Isrc/
src/lxplib.c:12:10: fatal error: 'expat_config.h' file not found
#include "expat_config.h"
         ^~~~~~~~~~~~~~~~
1 error generated.

Error: Failed installing dependency: https://luarocks.org/luaexpat-1.5.1-1.src.rock - Build error: Failed compiling object src/lxplib.o

it is probably a known issue from luaexpat ?! -> lunarmodules/luaexpat#32
but seems not solution yet.

Can someone help on this ? thank you 🙇

Do you already have expat installed on your Mac?

[windmgc]

If you already have expat installed but still encounter this error, I think follow this comment lunarmodules/luaexpat#32 (comment) is the best solution

thanks for reminding @windmgc , it work when I manually install expat via homebrew and assign the EXPAT_DIR properly.

Let me issue a PR to update the readme 🙇 thank you ( I guess it's worthy to remind ppl for some mac users)

see lunarmodules/luaexpat#33

This is a problem with the expat installation on Mac, that header is required to be available, since settings in it will have an effect on the ABI of the compiled lib.

@Tieske Seems the PR is still pending, can I say your PR can fix this problem permanently?
