Description
Why curl localhost always return "500 Internal Server Error".
I followed the example of ngx.balancer :
https://github.com/openresty/lua-resty-core/blob/master/lib/ngx/balancer.md
Error : failed to run balancer_by_lua*: /usr/local/lib/lua/resty/core/base.lua:24: ngx_http_lua_module 0.10.19 or 0.10.20 required

Research direction
Start with the ngx.balancer documentation linked in the issue, then inspect lib/resty/core/base.lua and lib/ngx/balancer.lua around the reported require path. Reproduce the curl request and compare the installed ngx_http_lua_module version with the requirement shown in the error; done means the example runs without the 500 response or the compatibility limitation is documented.
