please help me, thank you.

What version of LuaSocket are you using? How did you build & install it? Are you sure you built it against the same Lua headers as the version of Lua you are running?

Happy to look into this if there are further details and you can answer questions. It still seems like this is a miss-match between the headers you are building against and the Lua you are running. Comment back with info if there is still something that needs addressing here.

I got the same problem on my Mac too.

I install LuaSocket 3.1.0-1 via luarocks with following command: luarocks install luasocket Lua version: 5.4.3 Mac version: macOS Sonoma 14.2.1

@tenpend How is your error related to OpenResty? What command or code are you running that shows that error? If it isn't OpenResty related please open a new issue report for your situation.

Yes, I'm running my code inside openresty.
