nginx @1.21.6+lua: lua_load_resty_core failed to load the resty.core module

[ryandesign (Ryan Carsten Schmidt)]

This appears in my error.log when I start nginx if it has been built with the +lua variant:

2022/05/12 02:19:49 [alert] 18057#0: detected a LuaJIT version which is not OpenResty's; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty's LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)

I haven't yet tried to use any lua directives so I don't know whether they still work despite this message.

I tried content_by_lua_block and it did work. So I'm not sure what significance the error messages have. Maybe some other part of the lua module needs resty.core and would fail. But if not, maybe the message can be silenced somehow.

Unfortunately, nginx now refuses to load if built with +lua.
